As it should with a 7 pole motor over the stock 3 pole motor.  Just as 5 pole motors and skewed armatures became the norm in HO scale.  The more poles a motor has, the smoother it will run.  The huge AC motor in my Scale Craft 4-6-0 is a 7 pole motor.  But with its gear box, she is a noisy beast.  I am anxious to get a tender behind her and a load to pull.

I plan to as soon as the rest of my track arrives today so I can finish my loop,  I dont have a tender for the engine yet, so it will just be the engine running by itself for the moment.

Your normal Lionel OO Hudson uses a 3 pole motor made in house at Lionel, also used in a couple accessories later on.  They can be a bit noisy and not as smooth at slow speeds.  Back in the day, companies offered upgrades to the popular locomotive to improve it.  This big motor is one of them.  It restricts the radius as it hangs way down low and to tight of a curve allows the spinning communtator plates to hit the flange on the trailing trucks rear axle.  Even the factory ash pan has to be eliminated to fit this beast of a motor.  But its very smooth, quieter than the stock motor and has bushings supporting both ends of the armature.  Even the cab floor of the body shell has to be extensivly ground out for the motor to fit.  But back in the day, these were not collectables worth hundreds of dollers, just a model to be used on ones railway as he or she saw fit. I bought this originally as a parts donor, but now I am putting it back together to run.  It barely will go around my 42" diameter, it has to be perfectly flat track wise, a dip at the joints lets the flange find that spinning motor again.  Mike
