As we know, the lift of the BNSF ban caused Tehachapi two have to mutually exclusive versions of the ES44. One must be disabled else the game crashes as two DLC occupy the same namespace. (Just saw a "Tehachapi crashes" thread on Steam again...) Suggestion: Remove all files from the ES44AC (Unbranded) depot, leaving just a folder "EmptySteamDepot" (as the depot itself cannot be deleted). No one needs an unbranded loco if the branded one's available.
