smaller non-linear rout through southeastern pa since dovetail gave up on steam routes, this will be a diesel route set in the early 70s./late 60s. it will include the sw1500, fp-7, and the gp30 coal wgons and pushpull cars .
I don't want to sound bad about the idea as it sounds Great but the problem with the time period is that it is a bad time and I say bad only because the Reading Line wasn't a small linear line as you would think the area is known as the Great Lehigh Valley and is a Major railroading town to this day as it connects NYC to Chicago by rail the only railroad running in the area at the time, Penn Central, Lehigh Valley & Central New Jersey had trackage here as well. SW1500 is a good choice but not the GP30 I say that only because DTG will just reuse a GP unit and paste the Reading scheme on it a call it as it is. Other Locomotive I would say is Alco C632. Biggest problem honestly is figuring out track plans and track side structures as the Time period you say trackage was moved around a lot here trying to figure out where it was originally to what a business looked like is super hard especially for a company like DTG I've lived here all my life and I'm in my upper 60's and still don't know where things are or where they were. I would say perfect Time Period is early 80's when Conrail ran thing's here as there is a lot of information and pictures that can back things up on said build.
