Rick, John thanks for chiming in here. I now see it in the manual. The product number of the engine is 6-11321
My first inclination was dirt and I cleaned the wheels and pick up rollers.
Its strange, I went to the layout to count the # of blinks and it was 4. I shut it down for a minute then restarted it just to double check I counted the blinks correctly. There were no blinks this time and the engine ran perfectly for a few minutes. I also turned off the smoke units ran a lap then turned on the main smoke unit ran a lap then turned on the Aux smoke, and both worked as expected. It ran for a another minute then just decided to come to a slow stop and was unresponsive.
Although it ran smooth I'll check on the brake shoes. Looks like need to remove the boiler and check the wiring and for any loose connections as well as making sure the motor and drive train are ok
any other leads from this update will be helpful
THANKS Steve
