Richmond and Tahoe Railroad

This beautiful live-steam locomotive, constructed by Mammoth Locomotive Works, is reminiscent of centuries past when the world seemed less complex even if the hundreds of parts in the locomotive were a little more difficult to understand.  Our working knowledge of live-steam locomotives is extensive:  We construct amusement-park size locomotives and consult on every aspect of their operation as well.
