Travel with Pentrex to the busiest freight mainline in North America. Union Pacific’s Kearney Subdivision lies in the heart of central Nebraska. The 110-mile portion from North Platte to Gibbon Junction can see an average of 100 trains a day. In 1999, Union Pacific completed construction of a third main track to ease the congestion. Pentrex cameras captured some awesome railroading action here, including many meets and passes. This is Class One railroading at its best! Many different types of trains are seen rolling across the sand hills and between farm fields. We take extra time to view trains rounding Buttermilk Curve, the best spot for watching trains on the line. Coal shipments are a big reason for the increase in traffic on the Kearney Sub. But with the world’s largest classification yard at the west end of the line in North Platte, many freights traverse the triple track too. Ninety-two different trains are captured running along the triple track with all kinds of motive power utilized, including distributed power coal trains. Pre-merger power can also be seen, including C&NW, Southern Pacific, and Rio Grande! You won’t want to miss this show!
