The BNSF/UP Joint line runs from Denver, CO to Pueblo, CO, with trains from both railroads running between the two cities. The line is dispatched by both the BNSF and the UP. The joint line begins as a triple track railroad at milepost 3.6 in South Denver through milepost 12.2 in Littleton, and then becomes a double track (though largely separated railroad) to milepost 52 at Palmer Lake. From Palmer Lake to Crews, milepost 84.4 the railroad is single track, with passing sidings at Monument, Academy, Colorado Springs, and Kelker. This single-track railroad can at times create a major bottleneck to operations. From Crews, milepost 84.4 to Bragdon, milepost 108.6, the railroad is again a separated double track line. Track 1 refers to the west most track, and generally is used for southbound trains. Track 2 refers to the eastern most track, and generally is used for northbound trains. Primary traffic on the joint line are BNSF and UP Coal trains, with coal loads usually running south and empties returning north, though some merchandise traffic is run. Pushers are still occasionally used, but DPU has largely replaced the pushers.
BNSF 5954 leads a typical joint line train, southbound at Palmer Lake, CO on June 11, 2006.

Trains can usually be heard from the triple track in Denver to about Monument, with dispatcher traffic heard from all portions of the line. Two road channels are used for the joint line, 160.920 MHz (UP Dispatchers) and 160.650 MHz (BNSF Dispatchers). Trains switch to 161.100 at Englewood, and may use 160.695 to talk to the Denver yard. Talking detectors at or near Louviers, milepost 21.3 Track 1 and milepost 21.9 Track 2 and a second detector at Castle Rock, milepost 35.0 Track 2, can normally be heard. The BNSF Brush Subdivision runs northeast out of Denver to Brush. This line is a single-track line with passing sidings. Traffic on this line consists of coal trains (connecting with the joint line) with loads running south and empties returning north, merchandise traffic, and Amtrak #5, running west in the morning, and Amtrak #6, running east in the early evening. The BNSF Front Range Subdivision runs north from Denver to Cheyenne, passing though Boulder and Fort Collins. This line is a single-track line with passing sidings. Traffic on this line consists of BNSF merchandise trains, though traffic is generally light. The UP Moffat Tunnel Subdivision (through Moffat Tunnel) runs west from Denver, and is a single-track railroad with passing sidings. Traffic on this line consists of UP coal trains, with loads running east and empties returning west, an occasional UP merchandise train, BNSF merchandise trains, and Amtrak #5, running west in the morning, and Amtrak #6, running east in the early evening.
