You can hear the whistle blow
The Nevada Southern Railroad Museum is located at the west end of Boulder City, just north of U.S. 93. There is no fee to look around, and if you say "howdy" to one of the volunteer engineers, like we did, they may even give you a quick tour. A Nevada state park, there is no admission, though donations are accepted. Train rides are every Saturday and Sunday, departing at 10:00, 11:30, 1:00, 2:30. Currently, rides are about 40 minutes, but once the I-11 bypass is built, they will be longer as the extended tracks cross U.S. 93 north of the Railroad Pass Casino. In December, there is also have a special Santa Train. The track they run on was originally built to support construction of Hoover Dam. ( The last few eastern miles of rail have been turned into the Historic Railroad Trail )
The restoration / maintenance shed is west of Yucca St., and also contains a model railroad, and various antique model trains for sale.
East of Yucca St. is where the full size engines and cars are located. Depending on how much you geek out, you could easily spend two hours there. Each engine / car has a very detailed info plaque, not only describing the type of engine / car, but also the history of the specific unit on display.
