Colorado's Joint line runs between Denver, CO and Pueblo, CO, passing through Colorado Springs, with trains of the BNSF and UP traversing the route. The line is a separated double track for much of the route, with single track between Palmer Lake and Colorado Springs.  Steep grades slow trains in both northbound and southbound, with the top of the grade at Palmer Lake.  Virtually all southbound coal loads as well as many northbound coal empties have DPU's to assist.

The famed Moffat Tunnel Sub runs west from Denver, CO towards the Rocky Mountains, where the lines goes through the mountains, not around them.  With 29 tunnels in the lines first 41 miles (the 29 tunnels are located in just 17 miles), the single track line features abundant photo opportunities.  The Moffat Tunnel Sub runs between Denver, CO and Phippsburg, CO for a distance of 168 miles.  Although a UP line, trains of the BNSF along with Amtrak are seen on the Denver to Bond portion of the line.

Major changes are in the works for one of the last single track sections of railroad located on the ex ATSF, now BNSF mainline across New Mexico.  This short single track section of railroad features 7 bridges in the short 4.7 miles from East Sais, NM to Scholle, NM as the railroad passes through Abo Canyon.  Work has begun on double tracking this bottleneck, which will improve operations on the busy transcon.  This gallery features images from the Belen, NM area to the Mountainair, NM area.

Between Des Moines, NM and Trinidad, CO, the Twin Peaks sub is quite scenic, passing through small ranch towns, going around many horseshow curves, and traversing the high plains of Colorado and New Mexico. Beginning in 2005, the line is used for northbound trains only, with southbound trains traveling through La Junta and onto the Boise City Subdivision en route to Texas.

With a train density that has to be seen to be appreciated, the Powder River Basin puts on a display of railroading at its finest.  Unit trains, modern power, DPU's, multi track operations, grades and curves, its all to be seen on the Orin Sub in Wyoming.

Lines of the BNSF and UP that serve the Powder River Basin fan out in many directions.  Crawford Hill in Western Nebraska features one such line.  The double track line utilizes manned pushers for Crawford Hill.  The Ponderosa Ranch welcomes railfans with its "Bed and Breakfast" atmosphere, and provides the perfect view point to watch the action.

Located in Eastern UT, this branch leaves the UP mainline at Brendal, UT.  Running south from Brendal, the line passes within several hundred yards of the entrance of Arches National Park.  This relatively unvisited line sees a once a week train each Friday, passing spectacular red rocks and even arches on its way to the mine at Potash, UT.
