While I was in northern Wisconsin a few weeks ago, I made a point of visiting two old railroad depots. Both are now museums run by local historical societies.
The depot at Mercer, Wisconsin, was built in 1906, and served passengers on the Chicago & North Western Railway. It’s the only remaining railroad depot in Iron County.
The folks at Eagle River have done a wonderful job restoring the depot there. It was built in 1923, and houses a nice collection of railroad and local artifacts. Its parking lot is also the northern trail head for the Three Eagle Trail, a recreational trail built on the former Chicago & North Western rail bed.
