The Duvarney layout's a 1:48 scale thing of beauty, a perfect venue to view and operate some of Marty Magregian’s excellent custom built steam locomotives, among others this newly completed Southern Ls-1 mallet, built as a donation to the RMCA club.

Using prototype photos and company plans Marty started with an OMI Y3 chassis and determined that a salvaged B&M R-1 Mountain boiler was a good facsimile for the prototype due to its smaller diameter than the Y3s. Extensive modifications were made to the handrails, valve gear sets, piping, domes, adding a custom built cab, a rectangular road# plate to the smokebox door to match the specific prototypes road# 4019 as well relocating the headlight from that spot to the pilot platform per the engine’s final service configuration.

Per Marty there were a number of contributors to the model specific to the drive mechanism too; I recall the drive/gearbox was a Doug Cockerham rebuild done some years ago with frame axles most recently modified by Rod Miller with roller bearings (my apologies for any inaccuracies or omissions.)
The big payoff on top of it’s appearance is it runs like a Swiss watch, easily handling some thirty plus cars. Interestingly Marty went with the suggestion to put a small HO Boiler Barker speaker in the smoke box rather than the usual tender “Boom Box” which was surprisingly more than adequate in volume and tone, quite realistic sounding. Stay tuned, more to come.
