Will Union Pacific 3985 be restored?
It is one of 105 Challengers built for Union Pacific between 1936 and 1943 and was, for many years, the only operating engine of its class in the world – the largest and most powerful operating steam locomotive. That title has transitioned to Big Boy No. 4014 now that No. 3985 is retired again.
