I'm sure this question has been asked once before but I don't feel like sifting through 7350 posts so I'll ask again.
Why are the 777's 4 cars instead of 3 despite only being only a couple of feet longer. Surely by having 3 cars and the same length as the new trains they would have a higher capacity as there would be one less gangway. For a 4 car train the 777 is very short. The only reason I can think of such short coaches is due to tight turns on future network expansions. Couldn't be because of tight turns on the current network because the 507/8's had longer coaches and have been fine. Also why are the driving coaches longer and only 1 door per side, again I have no clue for this because it wont effect door opening at the likes of Green Lane because the front and back door still wont open as an 8 car set.
