Turnout builders might profit by looking up an article by once noted MR author Jack Work, on building turnouts in place. This describes a way to build turnouts to any combination of curves that you ca

Narrow Gauge Shay sizes depended on their users. Eastern U.S. NG operators did tend to keep to the smaller sizes. A roster of the 36" gauge 50-2 Shays has been given, but there were a couple dozen lar

Nigel This just gets more interesting. Your photo shows framed bents on pile foundations, a fairly common solution for high trestles erected over soft ground, but it looks like the framed bents were m

Tony Attached is a 1911 article on the Berninabahn,s self propelled Rotaries. Apologies for the reproduction quality - these are scanned off of 30 year old Xeroxes. And no, I don't read German, beyond

Thanks again Tony This has been very interesting and informative. There are not many who follow up on exported sales, much less on foreign production. Would you like a copy of the Bernina Bahn' Meyer

Tony Thanks again for the photos and details. Since you did not mention it, I will add that the meter gauge Transandian Rotaries, both the FCTA and FCTC machines, had 3-axle lead trucks. This not only
