A steam locomotive that’s been sitting in Pomona since 1962 at the RailGiants Train Museum is set for revival. Union Pacific steam engine No. 4014, also called “Big Boy,” was built in 1941 and was put to rest in 1959 after it traveled more than a million miles. It formerly carried 3,600-ton freight trains over the Wasatch Mountains, which ran through Utah and Wyoming. The locomotive will be converted to run on fuel oil rather than by coal. The revival of Big Boy is expected to take five years. After this, it will tour the country on Union Pacific’s more than 35,000 miles of track, which connects approximately 7,000 cities.
