With DTG's recent announcement of producing their own Tehachapi route, something I'm not entirely surprised at given my lack of participation of late, I've been thinking of what to do with the 3DTrains version. Although I believe DTG's offering will be well received, I don't wish to abandon the project outright, and while it's been long since I've updated the route, I thought perhaps a different approach was needed and I would like to get feedback and suggestions on how to best handle this situation; especially to not leave those who've supported 3DTrains over the years in limbo with a useless product on their system.
One idea I have is to backdate the route, maybe as far as 60 years or so. Except for surrounding buildings, which are relatively easy to alter, little has changed in track arrangements between the 1950s and mid-1990s, and depending on the era chosen (my preference would be with 1st-generation diesels for obvious reasons), minor expansions would be necessary to bring the yards at Mojave and Bakersfield up to par, remove notches from tunnel portals, and change out the scenery to suit. Any new alteration would be stand alone from what I have so far, and the modern version will continue until all bridges, signals and modern scenery are complete.
