Hi,

I have Bachmann FT-A and FT-B units and have run into a strange problem. I am still in the process of building my layout so to test run I used my son's layout. (The B unit was a present from my kids so only a recent arrival.) My son't layout has a fairly steep rise round a 22" curve. Normally I never have problems but while pulling 4 passenger cars, the B unit seemed to just jam at about 90% of the way up. I gave it a little push and it got going again till it got to about the same point on its way round again and the same thing happened.

I used just the B unit to pull the cars and it had no problems. Put the A unit back and got the lockup. I reversed them and had the B unit in front and this time the A unit locked!

Does anyone have any ideas why the 2nd unit in line seems to lock the drive when being pulled up a hill? Is there a grease I could use on the drive train that may help maybe?


Thanks


Warren
