Brand new in here and loving the sim so far. One suggestion I have is that you consider the commuter line Penn Central (and now Metro North) runs from Grand Central Terminal in Manhattan to Brewster, Connecticut. If you can simulate the FL-9s that used to run on electric for part of their route and then switch over to diesel, it would be amazing! The late '70s -early 80's might be a great time when the FL-9s were in their respendent blue and yellow among the commuter M1s and MUs. They repainted some in the striking New Haven RR scheme as well!!
