............ but the train is almost certainly not going to be held, and it would not be possible to request it.
....
I agree, but in days of old, really pretty damned old, 'tis true, it did happen.
I remember reading somewhere (and even that was a decade back) that the morning train from Silloth used to arrive at Carlisle either a minute or two late, or perhaps precisely when, the first (I think) morning Euston departure was leaving. It would have been, presumably, around 06.00.
Apparently, a kindly worded request to the station master at Silloth would usually mean the Euston train would be held back for the odd long-distance passenger.
Of course, for a keen crew, it would not have been a big problem. The Lizzie at the head of the London train would have had a bit in hand, and nothing like the pathing difficulties of the modern railway south of Crewe.
Not sure when the last passenger from Silloth could have availed him/herself of this unofficial customer service benefit - not much later than 1960, I'd guess.
