Agreed. Another thing to note is that the WDP4 tackles this issue by having the 2 TMs as far as possible from the Centre of gravity of the loco, so that the Torque due to the TM's weight can offset the reaction torque, thereby improving the weight transfer characteristics of the locomotive. This approach however creates a minor problem as the trailing wheel in the front bogie, the one which has the maximum weight transfer, is now un-powered and cannot be controlled effectively to mitigate the slip. However, this will only be a minor nuisance and not a serious problem because of the EMD's creep control system, but it does show that such a wheel arrangement is a tricky thing to manage.
