Youd better have a look at History of rail transport too Both articles include a fair amount of information up to the mid th century and then tail off rapidly John by all means add whatever history you have at your fingertips to whichever article seems most appropriate The more that I look at this hierarchy of articles the more I realise that we railway enthusiast editors have been very good at detailing all the nittygritty branch line and loco type articles and not so good on the genuinely enyclopaedic ones such as these I dont think were going to run out of stuff to do in the near future
