Thank you for your request which we received on 18 March 2023.
Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. I can confirm that we hold some of the information you require. You asked:

Please see the attached spreadsheet that shows arrivals and departures from Amersham for the period requested. This includes the scheduled arrival / departure times where available, compared to the actual time the trains arrived / departed. Unfortunately there are some data quality issues at the location, and these will be resolved when the signalling is upgraded in future.
Unfortunately train cancellations are booked at the location the train is cancelled or withdrawn, and therefore we cannot link them to a specific branch of the line. These cancellations/withdrawals do have the cause logged against them, but they cannot be linked to a specific branch.
There was one weekend of a planned closure, which meant there were no trains to Amersham. This was on 4 - 5 February 2023, when the entire Metropolitan line was suspended.
If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.
Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.
Yours sincerely
Eva Hextall FOI Case Management Team General Counsel Transport for London
