Building the Railroad Empire

In contrast to what is present, this model lacks the cross members for tenders connecting to trucks, water fill port and cap, water line and anti-syphon linking injector to tender, steam lines and valves in cab or turret supplying steam to appliances and gauges, air brake steam lines and controller, rear tender coupler, a headlight (with my personal experience of a knee injury from leading people in the dark), window frames that open, and a mechanism to prevent coal spillage from the ramp in the tender. Additionally, there's no steam turbine for powering a headlight and I've only found a picture of a unique 2-4-4 but not other 2-4-2 variations. Lastly, more detailed descriptions of wheel and tire mounting on axles, particularly drivers, could be considered.
