Locomotive Service Bulletin 2022 #1/ Bachmann Plus F units

 Greetings All,

Welcome to the first Shop Service Bulletin of 2022. Hopefully you will find this helpful.

Locomotive Service Bulletin 2022 Number 1


From: Terminal Yard Engine Shop

To: All Locomotive Shops

Subject: Bachmann Plus Locomotive Power Truck Issues

1.    Routine servicing of Bachmann Plus EMD F7A and F7B locomotives revealed that the power trucks on several units were not transferring power from the wheels to the motor.

2.    Causation has been determined to be the ground side power strap not properly grounding the locomotive due to the chemical black applied at the factory. This power truck is from an H16-44 and is similar to the F7. 


To restore power from the truck to the motor pry off the truck side frame at the front or rear of the truck. Remove power strap by loosening small Phillips head screw and lightly sand off the black coating where it contacts the wheels and locomotive frame. Lightly sand the frame where the power strap makes contact.

3.   For System Wide distribution.


Thanks for reading!!!
See you soon!!!

    Acknowledge chemical black coating as cause of unwanted grounding. We greatly appreciate the easy solution should this problem be detected on locomotives at West Mill.

    Thank you Sir John for the helpful tips with the Bachmann power truck grounding issues. I have some Penn Central units that this would apply to 😊👍🚂
