A lot of stuff I've read stated that 1972mkI tube stock was really awful in terms of driving performance; most of what I've read states that it was down to the fact that it was a manually-operated 1967TS with some components nicked from scrapped 1938TS, and that the resulting mismash provided a rather poor driving experience for the person on the front.
Is most of this conjecture and rumour, or were the 72mkIs really that awful to drive? And how did they fix it (mostly) for the 72mkIIs?
I drove them for a few years on the northern before they were withdrawn and i liked them. If you got a good unit like anything they were good to drive if you knew how to handle them.
I know the mkII's have either the door engines or vavles from the 38 stock but these are being replaced by metronet at the moment.
Had a few times i fell off my seat when driving, mainly because of the rubbishy track on the northern. And had a woman yell at me because she did as i came out of the colindale tunnel at a rate of knots. There's a bit of dodgy track there and the 72's liked springing all over the place!
