i had a thought that there could be a route for Colorado as a person who lives in the state i think there should be a Colorado route. we already have DRGW routes in game but why don't we have routes in the state that it was made in. we also have the iconic Moffat tunnel and they could make a line from Denver yard to salt lake. there also could be a line to kanas from Denver yard on the Limon sub and that could open opportunity's to make a lines in kanas and if rights are granted there could be some KCS routes. another route could be Denver to Cheyenne. depending on what route they would want to make here's some locomotive suggestions. they could add some of the DRGW steam engines like non articulated locomotives M-68 northern T-29 10 wheeler P-44 pacific articulated locomotives L-105 with the rock shield L-97 challenger L-131 mallet most DRGW diesels have been covered in Train Simulator but heres some that could still be added VO660 ML4000 RS3 H-10-44 S-2 there also could add the Rio grande Ski train with cars thoughts on this idea?
I agree, Colorado is a state rich with railroad history and it's a bit of a shame there isn't more Colorado based routes available for TS outside of Raton Pass and Clear Creek. I think a good route to include would be a steam era/transition era Royal Gorge route. It would be adding an iconic route that features some of the best scenery Colorado has to offer, while also featuring motive power (standard gauge Rio Grande steam) that's gone rather unappreciated over the years.
There is not a licensing issue with Canadian Pacific and as CP now own KCS there should not be any rights needed to be granted. There are KCS repaints (SD40-2, GP40-2, SD70 ACe) on the RWA and other sites. The DRGW steam and diesel locos you list would require a large investment in developement however third parties have developed the Alco S2 and RS3 and there is a superb Fairbanks Morse H10-44 in developement although none are in DRGW liveries. DRGW is not seen by most of the community as being a high priority livery but if requested via the right forums there are repainters looking for a challenge (I am not one of them!). The Ski Train is available as repaints see the RWA library.
