Brian McBride Chair

Dear Shareholder,

Trainline plc ("Trainline" or the "Company") will be holding its Annual General Meeting (the "AGM") on Thursday, 30 June 2022 at 120 Holborn, London, EC1N 2TD with the meeting set to start at 10:00 am.

The official business of the AGM is set out on pages 6 to 8 of this notice of AGM (the "Notice").

AGM arrangements and voting

The Company's board of directors (the "Board") is pleased to invite shareholders to attend the 2022 AGM at our London office, 120 Holborn, EC1N 2TD, in person. We value the opportunity to engage with our shareholders and look forward to seeing those of you who are able to attend.

Your vote is important so I strongly encourage you to submit a proxy vote in advance of the AGM and appoint the chair of the AGM as your proxy with directions as to how to cast your vote on the resolutions proposed, even if you intend to join the AGM in person. The notes on page 9 explain how you can submit your proxy vote electronically. Alternatively, if you are not equipped to submit electronically, the accompanying proxy card provides details on how you can submit your proxy vote by post.

If you have any questions that relate to the business of the AGM, I invite you to submit them via email to investor@trainline.com before the AGM takes place. We will maintain a list of responses to frequently asked questions in relation to our AGM on our website at https://investors.thetrainline.com/AGM.

Should the UK Government's public health guidance and legislation require changes to the format of the AGM, this will be notified via our website at https://investors.thetrainline.com/AGM.

Directors' remuneration policy

The Remuneration Committee has spent considerable time reviewing how Trainline's remuneration structure, approved at our 2020 AGM, can fully motivate the Executive Directors to deliver exceptional performance for shareholders, reinforce Trainline's ambitious long-term growth targets, address how certain external developments outside of the Company's control have made the roles of the Executive Directors far more challenging and ensure that Trainline can attract and retain talent in what is an extremely competitive sector. The Remuneration Committee concluded that the fundamental structure of the remuneration package is appropriate but that some changes are required to the Performance Share Plan structure.

The Chair of the Remuneration Committee wrote to our largest shareholders, representing 78% of total voting rights, to consult on these changes to our Directors' Remuneration Policy and I would like to thank all those that took the time to provide their pragmatic feedback, which the Remuneration Committee spent significant time considering before putting forward the proposed 2022 Directors' Remuneration Policy (the "2022 Remuneration Policy).

The 2022 Remuneration Policy is detailed on pages 86 to 92 of the Company's annual report for the financial year ended 28 February 2022 (the "FY2022 Annual Report") and an overview of the proposed changes from the current shareholderapproved remuneration policy, which received 99.85% support at our 2020 AGM, are set out on page 4 of this Notice.

03

The Board and the Remuneration Committee strongly believe that the 2022 Remuneration Policy aligns with Trainline's strategy and culture, reflects shareholder commentary received, and will fully motivate management to deliver exceptional performance for shareholders.

I urge you to read the Chair of the Remuneration Committee's statement on the 2022 Remuneration Policy on pages 82 to 84 of the FY2022 Annual report and I hope that we can count on your support when you consider how to vote at the AGM.

Amendments to the Trainline plc Performance Share Plan Rules (the "PSP Rules")

The PSP Rules will need to be amended to be consistent with the proposed 2022 Remuneration Policy. Further information on the amendments being proposed is available on page 4 of this Notice. The resolution proposing the amendments to the PSP Rules will not be proposed if the resolution proposing the adoption of the 2022 Remuneration Policy is not approved.

Director re-election

As announced on 24 May 2022, Kjersti Wiklund has decided not to seek re-election at the AGM and will step down from the Board upon its conclusion. Kjersti has invested considerable time consulting with our major shareholders to develop the 2022 Remuneration Policy and has agreed with the Board that now is an opportune moment for her to step down. I would like to thank Kjersti on behalf of the Board for her contribution to Trainline and the considerable support she has provided in transitioning the business into life as a public company.

All other current Directors will stand for re-election at the AGM, in line with the provisions of the UK Corporate Governance Code 2018.

Having considered the performance of and contribution made by each of the other Directors, the Board considers each of them to be fully effective and committed to his or her role and recommends them for re-election.

Recommendation

The Directors consider all the resolutions set out in this Notice to be in the best interests of the Company and its shareholders as a whole. The Directors unanimously recommend that you vote in favour of all the resolutions set out in this Notice as they intend to do in respect of their own shareholdings, currently amounting to 0.5% of the total voting rights of the Company.

Brian McBride

Chair of the Board 25 May 2022

Summary of resolutions

Resolutions

Resolution 1 – Reports and Accounts

The Directors are required to present the annual accounts, strategic report, directors' report and the auditors' report on the accounts to the meeting.

Resolution 2 – Directors' Remuneration Report

The Directors' Remuneration Report for the 2022 financial year (the "2022 Remuneration Report"), which sets out details of the remuneration paid to the Directors during the year ended 28 February 2022, can be read on pages 93 to 101 of the FY2022 Annual Report. The vote is advisory in nature and therefore no entitlement to remuneration is conditional on the passing of the resolution.

Resolutions 3 – Directors' Remuneration Policy

This resolution is to approve the 2022 Remuneration Policy which is set out on pages 86 to 92 of the FY2022 Annual Report. The 2022 Remuneration Policy sets out the Company's forward-looking policy on Directors' remuneration, including the components of the executive and non-executive Directors' remuneration.

The 2022 Remuneration Policy will make the following changes to the current shareholder-approved remuneration policy:

• the PSP award opportunity will increase from 250% to up to 550% of salary, comprising a core award of up to 250% of salary and a kicker award of 300% of salary in FY2023 reducing to 100% of salary in FY2024 and FY2025; and
• a cap of 2.75 times the value of the FY2023 grant will be applied to the PSP vest-date values in FY2025, FY2026 and FY2027 to ensure that maximum remuneration opportunities reward exceptional performance but are not excessive or as a result of windfall gains. Any vesting of share value over and above the cap would be forfeited.

Pursuant to the relevant regulations, the Company may not make a remuneration payment or payment for loss of office to a person who is, or is to become, or has been a Director of the Company, unless that payment is consistent with the 2022 Remuneration Policy, or has otherwise been approved by a resolution of shareholders.

The vote on the Policy is binding on the Company. If this resolution is passed, the 2022 Remuneration Policy will apply to all remuneration payments made to the Directors effective from the date of this AGM until a new policy is approved at the 2025 AGM, except in the event that a change of policy is proposed or the advisory vote on the directors' remuneration report is not passed in any year subsequent to the approval of the policy.

Resolutions 4 – Amendments to the Trainline Plc Performance Share Plan Rules (the "PSP Rules")

This resolution will approve the amendments required to the PSP Rules in order to implement the proposed 2022 Remuneration Policy which is detailed on pages 86 to 92 of the FY2022 Annual Report.

The PSP Rules, including tracked changes, will be available to view on the Company's website at https://investors. thetrainline.com/AGM until the end of the AGM and also on the National Storage Mechanism. This resolution will not be proposed at the AGM if Resolution 3 is not approved.

Resolution 5 to 10 – Re-election of directors

In accordance with the Company's Articles of Association and the UK Corporate Governance Code 2018, all the Directors will retire and stand for re-election at the AGM, except for Kjersti Wiklund who is not seeking re-election. Resolutions 5–10 (inclusive) propose their re-election by the Company's shareholders. Biographical details of all current Directors are set out on pages 72 to 73 of the FY2022 Annual Report to enable shareholders to take an informed decision on their re-election.

The Nomination Committee has reviewed the independence of each Non-executive Director and determined that they are all independent in character and judgement and there are no relationships or circumstances which are likely to affect their judgement. The Non-executive Chair was considered independent upon appointment.

The Nomination Committee are satisfied that each Director devotes sufficient time to their duties and demonstrate great enthusiasm and commitment to their roles. All Directors, other than Kjersti Wiklund, are therefore recommended by the Board for re-election.

Resolutions 11 and 12 - Appointment of the auditor and remuneration of the auditor

At each meeting at which the Company's accounts are presented to its members, the Company is required to appoint auditors to serve until the next such meeting. Resolution 11 proposes that PricewaterhouseCoopers LLP be re-appointed as auditors of the Company to hold office until the conclusion of our next AGM.

Resolution 12 gives authority to the Directors to determine the auditors' remuneration.

Resolution 13 – Political Donations

The Company does not propose or intend to make political donations and did not make any political donations in FY2022, within the normal meaning of that expression. However, as the definition of political donations in theCompanies Act 2006 is broad, it is possible that normal business activities, which might not be thought to be political donations or expenditure in the usual sense, could be caught. This resolution is proposed as a precaution to ensure that the Company and its subsidiaries do not unintentionally technically breach the Companies Act 2006.

Resolution 14 – Authority to Allot Shares

This resolution is to renew the Directors' authority to allot shares. The authority will allow the Directors to allot ordinary shares in the Company, or grant rights to subscribe for or convert any securities into ordinary shares of the Company, which represent not more than one-third of the issued share capital of the Company as at 24 May 2022, being the last practicable date prior to the publication of this document.

Special Resolutions

Resolution 15 – Disapplication of pre-emption rights

This resolution would allow the Directors to allot shares for cash and/or sell treasury shares up to a set value without having to offer such shares to existing shareholders on the conditions as described on page 12.

Resolution 16 – Disapplication of pre-emption rights for acquisitions and other capital investment

This resolution would give the Director's authority to allot additional shares for cash and/or sell treasury shares up to a set value as described on page 12 without having to offer such shares to existing shareholders, in connection with an acquisition or other capital investment.

Resolution 17 – Purchase of own shares

This resolution will authorise the Company to make market purchases of up to a set number of its own shares as described on page 12 and specifies the minimum and maximum price at which the shares may be brought.

Resolution 18 – General Meetings

This resolution seeks to authorise the Directors to call general meetings (other than an annual general meeting) on 14 clear days' notice.

A further explanation of Resolutions 14 to 18 is available on pages 12 and 13.

Notes to the Notice of Annual General Meeting continued

CREST and Proxymity proxy appointment

1. CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy instruction service may do so for the AGM and any adjournment thereof by using the procedure described in the CREST Manual. These procedures are available via www.euroclear.com. CREST personal members or other CREST sponsored members, and those CREST members who have appointed voting service providers, should refer to their CREST sponsors or voting service providers, who will be able to take the appropriate action on their behalf.

For a proxy appointment or instructions made using the CREST service to be valid, the appropriate CREST message (a CREST Proxy Instruction) must be properly authenticated in accordance with Euroclear UK & Ireland Limited's ("EUI") specifications and must contain the information required for such instructions, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or is an amendment to the instruction given to a previously appointed proxy, must, in order to be valid, be transmitted so as to be received by the issuer's agent (ID RA19) no later than 10:00 am on 28 June 2022, or, in the event of an adjournment of the Meeting, 48 hours before the adjourned meeting. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time, any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

CREST members and, where applicable, their CREST sponsors or voting service providers should note that EUI does not make available special procedures in CREST for any particular message. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member, or has appointed a voting service provider(s), to procure that his/her CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In connection thereto, CREST members and, where applicable, their CREST sponsors or voting service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.

The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

If you are an institutional investor you may be able to appoint a proxy electronically via the Proxymity platform, a process which has been agreed by the Company and approved by the Registrar. For further information regarding Proxymity, please go to www.proxymity.io. Your proxy must be lodged by 10.00 am on 28 June 2022 in order to be considered valid. Before you can appoint a proxy via this process you will need to have agreed to Proxymity's associated terms and conditions. It is important that you read these carefully as you will be bound by them and they will govern the electronic appointment of your proxy.

Corporate Representatives

1. Only those shareholders whose names appear in the Company's register of members: as at 6.30 pm on 28 June 2022; or if the Meeting is adjourned, in the Company's register of members at 6.30 pm on the day two days prior to the adjourned meeting, shall be entitled to vote. Changes to the register of members after the relevant deadline shall be disregarded in determining the rights of any person to vote at the Meeting.

Any corporation which is a shareholder can appoint one or more corporate representatives who may exercise, on its behalf, all its powers as a shareholder provided that no more than one corporate representative exercises powers over the same share.

If two or more corporate representatives purport to vote in respect of the same shares: (a) if they purport to exercise the power in the same way as each other, the power shall be treated as exercised in that way; and (b) in other cases, the power shall be treated as not exercised.

Shareholder requisition rights

1. Only those shareholders whose names appear in the Company's register of members as at 6.30 pm on 28 June 2022, or if the Meeting is adjourned, in the Company's register of members at 6.30 pm on the day two days prior to the adjourned meeting, shall be entitled to vote.

Explanation of resolutions

An explanation of Resolutions 14 to 18 is set out below.

Resolution 14 – Authority to Allot Shares

This resolution will give the Directors the general authority to allot new shares, and grant rights to subscribe for, or convert any security into, shares, up to a maximum nominal value of £1,602,268, which is equal to approximately one-third of the issued share capital of the Company as at 24 May 2022, being the latest practicable date prior to the publication of this document.

The Directors have no present intention of exercising this authority but consider it prudent to maintain the flexibility that this authority provides. As at 24 May 2022, being the latest practicable date prior to the publication of this document, the Company does not hold any treasury shares. This authority will remain in force until the conclusion of the annual general meeting of the Company in 2023 at which the Company is likely to seek renewal of the authority (or, if earlier, at the close of business on 30 September 2023).

Resolution 15 – Disapplication of pre-emption rights in certain circumstances

This resolution would allow the Directors to allot shares, or grant rights to subscribe for, or convert securities into, shares, and/or sell treasury shares for cash without having to offer such shares to existing shareholders up to a maximum nominal value of £240,340, which is approximately 5% of the Company's issued share capital as at 24 May 2022, being the latest practicable date prior to the publication of this document.

Resolution 15, if passed, will allow the Directors to make appropriate exclusions and other arrangements to resolve legal or practical problems which, for example, might arise in relation to overseas shareholders. This disapplication authority is in line with the Pre-Emption Group's Statement of Principles 2015 (the "Statement of Principles"). Annual renewal of this authority will be sought in accordance with best practice and in line with the most recent Statement of Principles.

While the Directors do not currently intend to allot shares pursuant to the authority under this resolution. However, the Directors wish to ensure that the Company has maximum flexibility in managing the Group's capital resources. Further the Directors do not intend to issue, pursuant to the authority under this resolution, more than 7.5% of the issued share capital of the Company on a non-pre-emptive basis in any rolling three-year period, without prior consultation with shareholders.

This authority will expire at the conclusion of the annual general meeting of the Company in 2023 at which the Company is likely to seek renewal of the authority (or, if earlier, at the close of business on 30 September 2023).

Resolution 16 – Disapplication of pre-emption rights for acquisitions and other capital investment

This resolution would give the Directors authority, in addition to the authority granted in Resolution 15, on a non-preemptive basis, to allot shares for cash and/or sell treasury shares up to a maximum nominal value of £240,340, which is approximately 5% of the Company's issued share capital as at 24 May 2022, being the latest practicable date prior to the publication of this document, without having to offer such shares to existing shareholders for the purposes of financing (or refinancing, if the waiver is used within six months of the original transaction) a transaction which the directors determine to be an acquisition or other capital investment of a kind contemplated by the Statement of Principles.

There are no current plans to allot shares pursuant to the authority under this resolution, however, the Directors wish to ensure that the Company has maximum flexibility in managing the Group's capital resources. This authority will expire at the conclusion of the annual general meeting of the Company in 2023 at which the Company is likely to seek renewal of the authority (or, if earlier, at the close of business on 30 September 2023).

Resolution 17 – Purchase of own shares

This resolution will authorise the Company to make market purchases of up to 48,068,050 Shares, being just under 10% of the Company's issued share capital as at 24 May 2022, being the latest practicable date prior to the publication of this document, and specifies the minimum and maximum prices at which the Shares may be bought.

This authority will expire at the conclusion of the annual general meeting of the Company in 2023. Renewal of this authority is likely to be sought at the annual general meeting each year.

The Directors confirm that they will exercise this buy back authority only when, in light of the prevailing market conditions, they consider such purchases would result in an increase in earnings per share and would be in the best interests of shareholders generally.

Any Shares purchased would be effected by a purchase in the market and may either be cancelled or held as treasury shares, which may then be cancelled, sold for cash or used to meet the Company's obligations under its employee share schemes.

As at 24 May 2022, being the latest practicable date prior to the publication of this document, the total number of options to subscribe for Shares in the Company was 20.3 million (approximately 4.2% of the Company's issued share capital and approximately 4.7% of the Company's issued share capital if the full authority proposed by Resolution 16 was used and the shares purchased were cancelled).

Resolution 18 – General Meetings

Under the Companies Act 2006, all general meetings must be held on 21 days' notice unless shareholders approve a shorter notice period subject to a minimum of 14 clear days. Annual general meetings must continue to be held on at least 21 clear days' notice.

This resolution seeks to approve an equivalent authority granted to the Directors at last year's general meeting to call general meetings (other than an annual general meeting) on 14 clear days' notice.

The approval will be effective until the Company's next annual general meeting, when it is expected that a similar resolution will be proposed.

In order to allow for the shorter notice period, the Company will make electronic voting available to all shareholders.

The shorter notice period would not be used as a matter of routine for general meetings, but only where the flexibility is merited by time-sensitive matters and is thought to be to the advantage of shareholders as a whole
