Union Pacific 535 on the Coalmont Branch pulling a Rocky Mountain Railroad Club Excursion through Centennial, Albany, and Fox Park WY on September 15th, 1957. This is the last excursion our locomotive was chartered for and pulled 6 stock cars, an SP observation car faced forwards, 4 Harriman passenger cars, and an open gondola for the club to take wide action shots of the train as 535 chugged up the 2.5% grade to 9062 feet. The locomotive crept at a snail’s pace of no more than 20 miles per hour
