Two years and a lot of hard work has Big Boy #4014 sitting on the rails again!

According to Ed Dickens, head of the Union Pacific Steam Team, “the last time Union Pacific had an articulated locomotive disassembled for this level of repair was in the 1950’s.”

An articulated locomotive has one boiler sitting over two separate of engine units or “drivers”. The two engine units move independently of each other which allows the long boiler to negotiate curves which would otherwise prove impossible.

Of the 25 Big Boys that were built, all but 8 were scrapped, unfortunately.

Now there are two Big Boys in Cheyenne. #4014 now under restoration, and #4004 sitting as a display in Holiday Park, also in the town of Cheyenne.

The Big Boys could pull a 5 1/2 mile long train on level ground!
