There are couple of reasons to be circumspect about the NWSL gears. First off the new (and maybe original) Lionel gears are delrin not nylon like a lot of us assumed. Second is they are the wrong type of gear. The idler that contacts the worm is a spur gear and not a proper worm gear. That means pressure is applied to only part of the gear tooth instead of whole tooth. Lastly they appear to be very thin for the amount of torque they are expected to transmit.
NWSL gears are supposed to better because they are made of a delrin variant called Celcon. This plastic comes in different formulations with some preferred for gears. Second they are cut versus cast. This should make them better but they are still spur gears and the are still thin.
I have a few sets of delrin gears from SDP and could swap them out at any time but have chosen to wait and see what Mike R comes up with. The best scenerio in my mind is a completely redesigned gearbox that will just drop in.
