Smoother backwards...

[grahament]

I am troubleshooting an N scale loco..not Bachmann I must admit but i think the principles are the same. It runs MUCH smoother and faster backwards rather than forwards. I have done all the usual stuff, cleaning, lubricating everything...very sparingly...and its the same.

It is a Hornby Minitrix Evening Star.

Thoughts anyone?

If I prop up the front so all loco wheels are off the rails and power is only coming through the tender pickups, wheels run perfectly in both directions.

Any thoughts or suggestions welcome.

This is the best site I have found for Hornby Minitrix N scale locomotives.

Hornby stopped selling these over 20 years ago. They can only be found now on eBay etc.

A major cause of this effect is the worm gear or motor shaft shifting forward or backward due to wear on bearings/bushings or a part that is moving out of place.
