Smart animation! The 4-10-2 Alcos didn't last too long on either the Southern Pacific or the Union Pacific due to their inherent over-stiffness for both lines' curves. The UP tried out 4-12-2's before deciding that a single-expansion articulated (thus the CAC-Series 4-6+6-4's) could do the job better on the entire line.
Actually you need to give credit to Sir Horace Nigel Gresley for the valve gear design, it is not yours. I have a 1/8th sized Streamlined A4 of his design under construction with this Gresley 2:1 conjugated valve gear operating the centre cylinder.
