I don't know if Mr. Orr has died or is still around but very ill, but George Huckaby of CUSTOMTRAXX has taken over the Orr line...he knows his stuff! I suppose you could use investment casting on a small scale to make custom frogs and such.
I have a few Orr turnouts to play with but haven't actually installed any--I am trying to figure out how to adapt them to two-rail so I can use Orr turnouts on my switching layout, which will eventually feature both overhead power and diesel-electrics, which will require two-rail (unlike the PE, the SN didn't put trolley poles on their 44-tonners to trip signals) power. My current theory is to use the frogless Orr turnouts and make custom insulated frogs out of styrene or other non-conductive material, and include power-routing in the switch. That should allow the use of the single-point turnout without causing a short.
