Actually, there was one run of the E’s which had a motor that draws an large amount of current, compared to all other P2Ks. I don’t know if this was a manufacturing mistake or an attempt to make a more powerful motor. Best thing to do with such a beast is to replace the motor, easiest is to just use another P2K motor.
Have seen the flawed Blue Box wheels too, comes from the method used to manufacture them. This is why on the only Blue Box I intend to continue running, I have replaced the wheels with NorthWest SHortline nickel-silver wheels. You get a better formed wheel and better electrical pickup, at the expense of some traction. They also don’t collect dirt like the standard sintered Athearn wheels.
