It is well advertised in timetable booklets and at posters on stations indeed there was one station I'm aware of that First Capital Connect operated that had a poster advertising this fact before you even got past the gateline plus also had one on the platforms too.
That's all well and good, but it's of no use for someone who isn't familiar with the policies of a particular TOC. As I say, if the rail industry wants this behaviour/policy to not put them in breach of contract when people miss trains they arrive on time for, they need to ensure that the policy is made utmost clear from
before you before your ticket, regardless of how you buy it.
We've had this argument so many times, it's been done to death - If you're travelling then you make sure you're on the platform with time to spare, you don't and shouldn't just turn up whenever you feel like it because you think the doors close at the advertised departure time
It's been done to death, and therefore your view is correct? Seems an attitude that would find you right at home in rail industry policy making! It's all well and good saying you should be there on time, but even the best arrangements can come to naught sometimes. If the TOCs are claiming (wrongly) that they have to close doors before the advertised departure time to ensure an on-time departure, it is clearly revealed as nothing better than a half-truth, if not a lie, if they then depart early. I can understand them wanting to close doors early, but they can't and shouldn't go around departing early, as that defies the point of the policy then. Where there is a pattern of early departure, TOCs should adjust their door closing policies and not just take it as a boon to their financials (from reduced PPM failures and franchise timeliness penalties).
That time is the time that the train departs by and operators are quite in their right to close doors up to 2 minutes early especially for IC services at London terminals to ensure all passengers have boarded.
The departure time is, by definition, the time the train departs. If it departs before then, then it is early. Departing early makes a mockery of the idea of a "scheduled departure time", unless you are a kind of service that is reservation compulsory, e.g. Eurostar, Caledonian Sleeper, flights etc., with all passengers boarded.
If the TOCs publish their policies, fair enough. But they do far too poor of a job for their current approach to be even remotely acceptable. Equally, it is not necessary to close doors so early in, for example, the case of London Terminals. It would be perfectly possible to close most of the doors 2 minutes before departure, and to keep the rearmost door (or two) open for "late"comers, closing the barriers the usual 30 or so seconds before departure. But seemingly such an idea is beyond the wit of mankind...
Non IC services can start the process 20 to 30 seconds prior to departure time so no the OP was in the wrong and they should have know better as should a number of others here by their words...
The OP was in the wrong if they knew the policy before buying their ticket, and the doors closed early so that it would depart on time. But no, it did it to enable an early departure, and so it is very much the TOC that is in the wrong. That is
not OK no matter how many times you go blaming the beleaguered passenger.
If any TOC does the same to me - closing the doors early, departing early, resulting in me being delayed - but then refusing to pay the appropriate delay compensation, they should be prepared to find a County Court claim form in their letterbox, pretty sharpish. I can't comment for others in this regard, but I won't put up with, frankly, utter tripe and bulls**t. Luckily it's not happened to me before, as I always make suitable arrangements to be on time, but there is always the possibility it may happen, and especially so where a previous train has been delayed.
