Pennsylvania Railroad 3750

PRR 3750 is a preserved steam locomotive.

Biography
3750 was built in 1920 for pulling freight and passenger trains. It was considered the standard locomotive of America like all other K4s. Little else is known about it's career, but it was for a time repainted to look like PRR 1737, another K4. It has since been repainted back to 3750 and is currently on static display at the Pennsylvania Railroad Museum near Strasburg.
