These would be a phenomenal, fun addition to the game. -The ES40DCs were the first General Elecric Evolution Series locomotives delivered to CSX, around 2004. They are simply derated ES44DC's to 4,000hp. Today, they can be seen on CSX freights anywhere wearing YN3 & YN3b paint. These would add a new, more realistic experience to power choice, rather than having a redundant lashup of AC44s, SD40-2s and GP38-2s. -CSX ES44AHs are the backbone of the GE fleet and would probably be the most sought after units for this game. There are some minor differences between classes of units (ie. 700-839 have low numberboards, 840-999 with high numberboards etc.) but hopefully they will be looked after by DTG. -A small request for plain YN3 reskins for the available models (AC44, GP38, 40, 40-2). Alongside YN3b and YN2, YN3 is still an extremely common paint found on all these types. Thanks and keep up the great work DTG!
