But, bear in mind most of the old pre-70's era motive power has been scrapped by the time the 90's roll in (mainly because of fuel efficiency and maintenance issues). I think the -2's will be fine, as well as the U-Boats and the Century Series. Dash 8's a maybe, 70's very iffy. The handful of Alco's will still go like gangbusters, but thats about it I think. I think the SF will regret scrapping the Alligators.
