Montana Rail Link leaving Missoula

[900spg]

Here is a couple of shots of a Montana Rail Link leaving Missoula, Montana to head west. I'm not familiar enough with locomotives to know the model. Taken during the evening with a 100-400 hand held. Comments and criticism appreciated.

Should be a GP-35 originally built for the DRGW. Keep the trains coming.
