But sorting Platform 5 is not a small job, when you factor in design and construction, the elephant in the room is HS2, no one will do this for less than 10 years when Crewe is going to get ripped up. As for the 1 train an hour, are you seriously suggesting that you have a micro fleet of 390s of whatever length just for the Liverpool service? Virgin wouldn't entertain that. Waterloo was a bad investment, simple as.
As for the questions about the capacity, it cannot fit in the same path as the one in front exactly. The trains arent occupying Platform 5 for 5 minutes though. Train 1 arrives, train 2 cannot arrive until 3 minutes later, there is no way that you are going to couple the Pendos together in 2 minutes including the dwell and get out in the time of the original path. You are going to be 2 or 3 minutes later, whereupon you are not in the same path south of Rugby.
Stafford, so they get a stop in a different train then? Which one and how does that affect the timetable? As for me saying "may", that is twisting my words, I said that because I haven't gone away and looked at what it would do for the timetable. I doubt the signallers at Wembley will consider the minor constraint at Euston of only being able to platform a specific type of train the same way you do! It is all moot anyway as there is more chance of getting 6 numbers on Saturday.
