One comment regarding the exploded view shown as an example. What I typically do, if an exploded view diagram existed in pdf form (think pre-2020) I will use it and assign all the parts to that exploded view (meaning all PS-1, PS-2 & PS-3 mechanical / deco parts with appropriate call out numbers. For instance, take the Premier Big Boy exploded view list. There are I believe 5-6 different part numbers assigned to the trailing truck of the locomotive. Each part labeled as PS-1, PS-2, PS-3. This is because the detail level on these parts changed (got better) each time it was made. Same goes for linkages: nickel, satin, blackened, etc.
where I am going, is I would typically avoid using the exploded view diagram to determine which electronics package the loco was delivered with. Instead, use the “electronic list” to the far right when you land on the search redults page.
once again, the premier genesis was produced with 4 iterations of electronic packages: PS-1, PS-2-5V, PS-2-3V and PS-3. Mechanically speaking, those parts changed very little (aside from brass flywheel motors, striped flywheel motors, PS-1 coil couplers vs PS-2 coil couplers, etc.
Just want everyone to be aware of the insignificsnt things that hsunt my dreams and roll around inside my head everyday!
Thank you,
Mike
