This patch applies the Searchlight Simulations/MLWAudio GEVO-12 and 16N-710G3C-II enhancement packs to the BNSF and UP ES44s as well as the UP SD70ACe included with DTG's Tehachapi Pass route. The AC4400CW and GP40-2 are NOT currently supported by this mod, but the AC44 may be a bit more likely to receive support in the future thanks to other brilliant guys creating their own mods for that engine.

the BNSF ES44AC spawns in with just the coupler and engine sounds but the engine doesn't show up at all.
I don't know if this is a bug or something.
It has the coupler and engine sounds
It works fine for me. Bear in mind I also own Marias and Stevens Pass which use the same exact BNSF GEVO
