Even as late as 1954 the meal selections were priced with the budget-conscious traveler in mind: breakfast cost 65¢, lunch was 85¢, and dinner could be had for $1.00. Other railroad uses of the name Challenger The Challenger name has also been applied to the 4-6-6-4 type steam-driven locomotives, the first of which were designed by the UP and built by the American Locomotive Company between 1936 and 1943. Best known among these is Union Pacific 3985, one of 105 Challengers built for the railroad. Originally a part of the Union Pacific Heritage Fleet, it was taken out of service in 2010 and subsequently retired in 2020. In 2022, it was donated to the Railroading Heritage of Midwest America, where it is now being restored to operational condition. The dome car now called Challenger was built in 1958 by Pullman-Standard as UP dome coach #7015, the last such car built. It was reacquired by Union Pacific in 1989 and today operates as part of employee and other special trains.
