In December 1892, the Grand Island & Wyoming Central Railroad built a line running from the town to the tin mill east of Hill City.

The town included a boarding house, saloon, platform station, and commissary car for railroaders.

This turned Addie Camp into a small farming community;[2] however, some tungsten mining resumed during World Wars I and II.

[3] The former site of the town is in Pennington County and is located 2.7 miles (4.3 km) east of Hill City.

[1] There are only a few ruined houses remaining, which are located on the north side of the former railroad tracks and along an old gravel road.
