To repeat: The minimum connection time is a (somewhat conservative!) time that the railway considers is adequate for able bodied and able minded people to make a connection between trains at a station. This is the time at which the railway says "this is the tightest time we are confident to sell an itinerary for".
The minimum connection time isn't relevant, except perhaps in the minds of enthusiasts. It also isn't published if the customer books their ticket online or from a ticket machine and then checks NRE. The only way to even find it is to use a timetable leaflet - and sometimes they are missing, or contradictory, even from those.
But whether a minimum connection time is published or not is not relevant here. It isn't in the same way that Delay Repay does not need to be explicit that if you have an "agreed" 25 minute connection at EXD, have it shaved down to 20 by a late train, and magically bugger about for 19 minutes, then run like a devil and miss your connection, then you don't get your money.
I think you've just made that up.
It is very frustrating to be accused of making things up without citation or rebuttal, because it is your way of making me look insincere or false. I have not suggested you are making things up - I am merely taking you up on your points and rebutting them to the best of my ability, and would ask you do the same courtesy to me instead of just saying "you made it up".
In a former job I had, a colleague was responsible for cleansing our delay repay CRM and finding particular problem connections. I sat on a working group seeing what we could do about them (often, not much, but sometimes we got some wins!). The minimum connection times are really there for exactly the reason I stated, and are set to be on the conservative side for able bodied and able minded people who are not already oriented with the station, assuming they arrive at one extremity of the station and have to make a connection on the very furthest platform in the station away from that. They also are not set in stone. The minimum times for the "re-imagined" Birmingham New Street were lowered, for example - it's now 12 minutes, as opposed to 15. Liverpool South Parkway was more recently increased to 10 minutes from 7 minutes.
I thought people would already be aware of this, but for clarity:
'Delay Repay' is compensation for inconvenience arising from delayed a arrival at one's destination regardless of the cause.
Nope, it doesn't cover you if you leave your bag and it ends up in lost property and causes you a delay, or if you have a ticket mishap on the day and need to visit a ticket office to get it corrected, or get really confused by being on the railways for the first time and not know where to go.
Delay Repay doesn't cover you if you have a connection which is equal to or greater than the minimum connection time and still miss your connection, unless there are compelling extenuating circumstances, like being a victim of failed assistance (or even a slow, successful one), have any sort of disability which hampers your ability to adhere to the connection, or are misdirected by info screens or staff. None of these are suggested to have been in play here.
A connection time which is simply unrealistic as a result of delays is one such cause.
I don't consider 6 minutes unrealistic at EXD - you don't even need to go upstairs to see the summary board - and if you think it is then we are having a different discussion.
