This is what mountian railroading is all about!

Westbound BNSF 4120 throttles up as it leaves Larimore. If you look closely, you can see the tiny change in elevation inbound to Larimore.

Loaded grain slows as it rounds the bend in Arvilla. Even though it looks like it trailing off into the background, this was not a BNSF 'earthworm' grain train...

A Memphis, TN to Seattle, WA P train snakes it's way around a Garbage train on main one.

Poking out from the shadows, this empty unit coal train speed north.
