I had an OMI BL2 with a Kleinschmidt drive. It was awful and totally unusable with a DCC decoder. Basically it had a centrifugal clutch mounted between the motor and the drive shaft. It was supposed to slowly engage smoothly slipping until lock up when it became a solid connection. In theory it was supposed to let the motor turn faster than drivetrain for a smooth slow start and then have the drive train catch up as the speed increased and then lock up. The same thing in reverse as you slowed the motor the clutch was supposed slowly smoothly disengage allowing the drive train to slowly coast down until it reached the same speed as the motor. In practice it didn’t make smooth starts and sort of stuttered until it locked up very quickly. When slowing down it would disengage and then engage making for a stuttering slow down. I was fascinated by the concept and fooled with it trying to get it to work smoothly. I tried different oils, grease and even tried that sticky stuff the R/C cars use in their differentials. Nothing would smooth it out except a long heavy train made the stuttering of engagement and disengagement less noticeable. The only way to use it with a decoder was to lock it up totally and that defeated the purpose of it so I returned it to the seller. It seems to me it was old technology that would work only on DC and with a long heavy train.
