I understand what the issue is, but I feel like this should’ve already been fixed in a patch update. Just want to make it a more noticed topic.
This is a issue that SO MANY people are complaining about (myself included) and it still hasn't been fixed.

I was only bother to list the first few.
While this bug is still waiting for the official fix there is a workaround on TSW3, not sure if it works on TSW2 or not as the save feature is a bit buggy https://forums.dovetailgames.com/threads/class-377-london-commuter-back-door-open.64751/#post-613073
A workaround I’ve heard of is to spawn on foot and then take over the service you want to drive. It was said that the door bug only occurs when the player spawns in a train. I haven’t tested it myself though so take it with a grain of salt.
On the PS5 I can confirm that if you spawn on foot and take over a train at Victoria and at Brighton the door bug does occur. You can sometimes hear the doors slam open when the service time kicks in.
Don't know about PS5 but on Xbox One if you open the door before starting the service you are able to close it once set off
