Norfolk and Western 475 is at the "J" Tower at the Strasburg Railroad.

The "J" Tower was built by the Pennsylvania Railroad (PRR) and originally located in Lemoyne, Pennsylvania. This is one of only two surviving examples of early PRR wood frame two-story switch towers.

Built in 1885, the J Tower was situated in between the Cumberland Valley and Northern Central RRs to protect the crossing of the two lines in Lemoyne, PA. The tower originally controlled switches and signals using a 35-lever mechanical machine linked to cranks and pulleys that moved the switches on the rail line.

In the early 1980s a group of volunteers saved the building and restored it to its original appearance and its now located at the Strasburg Railroad.

Number 475 was the 101st of 125 M class steam locomotives built for the Norfolk & Western from 1906 to 1907, rolling out of Baldwin Locomotive Works in June 1906. It retired from active service in 1956 after completing 50 years of service. Number 475 is based out of the Strasburg Railway in Pennsylvania.
