While I'm revising the trackplan, I thought it would be great to look at some of the locomotives that are used on the Mission Mountain Railroad.
First up is the prime motive power on the line, WAMX #1501. #1501 is an EMD SW1500 switcher engine.

Besides #1501, the line also has WAMX #1214, an SW1200 that was once Northern Pacific #128. Photos can be found here (not my photos, credit goes to rrpicturearchives.net and original authors)
Then there is WAMX #3517 and WAMX #3807, both are GP38-2 units. Being road units, these engines will often work other railroads owned by Watco Companies.
Besides those, there are a variety of Santa Fe, Burlington Northern, Milwaukee Road and CNW units that work on and off, mostly GP units.
However, initial efforts will focus on #1501 since that is the railroad's prime mover.
