I'm a fan of electric locomotives and electrified railroads in the US and personally I'd like to see some well known routes that were once electrified and some that still are today. Plus it seems that there is sort of a shortage of US electrics in train sim. Here's a list of some routes that I'd love to see in train sim (in no order of importance): The Milwaukee Road pacific extension electrification The Virginian Railway electrification The Black Mesa and Lake Powell And The Keystone Corridor
These would be great. The Milwaukee Road and the Virginian would be fun, but you're forgetting one railroad: the New Haven. We could get a New Haven EP-5 "Jet" electric and commuter passenger cars. Also, a new GG-1 would be awesome for the Keystone Corridor.
Thanks for mentioning the New Haven, I totally forgot about it. I will like to mention two more routes that I will like to see also are: The Great Northern electrification through the Cascade Mountains And The BC Rail Tumbler Ridge Branch
It turns out that Gtrax is doing the GN electrification through the Cascades! http://www.gtraxsims.com/ This is great news.
