A screenshot straight from the factory:
Yes, this is the original Cooke Mogul base, and with some modifications we were able to recreate the Consolidation of the same design, introduced to Cooke in 1883 and delivered to DSP&P. A total of 20 Consolidation units were built between June and September 1883; and we particularly selected 4 units to represent in Train Simulator, containing basic differences and unique features, as was done on the Cooke Moguls.
