Well too late,i just got some wheelsets From NWSL the ones that were supposed to be out of stock.They are 40" wheelsets with the gear and they are exactly like the ones that came out of the old ones.So why did 4 of my Powered Metroliner units have 40" wheelsets¿I know an older fellow that works in the Wilmington Shops and he used to work on the Metroliners when they came into the shops for repairs.Monday when i go back to work,i'll pick his brain about the wheel sizes.Seems to me years ago,i can remember the wheels being hugh,but i could be wrong.I also ordered 40" metal wheelsets for the dummy metroliner cars so i can add lights,should get them in a few days.
