UP Cotter Bridge
Title:  UP Cotter Bridge
Description:  Union Pacific crossing the Cotter Bridge over the White River in Cotter, Arkansas on June 19, 1989, Kodachrome by Chuck Zeiler. Locomotives pictured are UP 117, 158, and 2178.

The bridge was built in 1903 by the Phoenix Bridge Company, and includes a 285 foot long turn span, deemed necessary by the Army Corps of Engineers as a result of river barge traffic, which in addition to moving commodities up and down the river, also brought in the steel for the constuction of this bridge. The river makes a 90 degree bend at this point. To the right, the railroad was built on the banks of the river for 40-50 miles or so, but to the left, the railroad ascends a steady 1% grade for the next ten miles. The first three spans to the right are level, as is the turn span and the first span to the left, but the next six deck girder spans begin rising at two plus feet in 320 feet. The total length of the bridge, not including the short five panel timber approach trestles at each end, is 1091 feet, 7½ inches. The turn span turned just once since built, for testing, and never turned again. The river barge traffic disappeared upon arrival of the railroad in Cotter.

Yard Derailment
Title:  Yard Derailment
Description:  Here's the scene and how it happened. The three locomotives (SSW 9647, UP 177, and UP 2537) ran across a switch in the yard, where the switch frog joins the rail of the track, the old rotten tie fell through, it broke in half, the frog fell through the tie and the rail broke out of it, coming up and knocking the brake shoe connecting rod loose from the rear axle on the fireaman's side of SSW 9647, and the rear axle jumped on top of the rail head. The rear axle was was knocked back over into the gage as I arrived. These two men drove up with the area wheel truck were at work repairing the brake rigging as the truck in the background unloads a new section of rail, a frog, and a few ties.
