I have "The Quarterer" NWSL cat. # 44-4, There's no doubt that having a quartering tool is next to absolutely imperative, if steam is your choice of motive power. I have had to pull drivers, and re-quarter them, on a couple of locos. Pricey?, yes, getting my locos running better, priceless! :mrgreen:
Both my HOn3, and On30 are freelance. Sag Harbor Shipbuilding and Drydock Company is the parent corporation of four shortline roads. Two are standard gauge, the "yard's" industrial is 3' gauge. SHS&D #1 is an outside frame compound 2-4-4-2, modified from an old Baldwin 2-8-0, by the shipyard. The yard's foundry, is casting parts for the outside frame 3' gauge 2-6-6-2, and if that loco is successful, they will start on the 30" gauge version for the Wiscasset Bucksport & Schoodic Point.
The "legal paperwork" needed to run four steam powered modern railroads, would require all four roads to make six trips each, to move the documents!
That's my story, and I'm sticking to it.
