Looking west from the same Interstate 90 exit ramp at Garrison, Montana, things become more interesting. The original main is straight ahead, with the former Northern Pacific Garrison station (now a Montana Rail Link office) just past the I-90 overpass in the distance. A wye connection to the Butte Short Line via Homestake Pass diverges to the left. At one time Garrison was an important transfer point for passengers, as the North Coast Limited took the Butte Line and most locals (and the Mainstreeter) traveled via Helena.
