Ruben Wells engine

The Ruben Wells is a steam engine on permanent display at the Indianapolis Children's Museum. Per Wikipedia:

The Reuben Wells is a helper locomotive that was built in 1868. It was designed to push train cars up the 5.89% incline of Madison Hill in Madison, Indiana, the steepest segment of standard-gauge main-track in the United States. Weighing 55 short tons (50 t), it was the most powerful locomotive in the world at the time. It is 35 feet (11 m) long. The train is named after its designer, engineer Reuben Wells.

The display area is so dark its a challenge to get a decent photo.
