Hi,

I do use a Powercab for DCC. The track is ez-track which is glued down so there are no track pins just a curve and a slope. 

The problem occurs at a point where all cars are on the curving slope, that is where the load hits the max. When the 2nd unit stops, the wheels are jamed and need to be rocked to release them so it is definitely a mechanism problem which may be a product of the removing and replacing of the motor during the decoder fitting. ie: the motor may not be in the exact same place which could be causing jamming.

At least that is the conclusion I have come too. When I get time I will try to investigate further so I understand the drive mechanism better. In the mean time I will just run it backwards  .

Looks like I have a work round. Someone suggested I try running the B unit backwards and see if that helped and it works perfectly. There must be something in the drive of the B unit that doesn't like being pulled in the forward direction. The pull comes from the A unit when the load is greatest on the incline. Didn't fix it but so far has solved the problem. 

Hi,

All of the wheel are on the track and I can remove the front unit and then I have to rock the locked up one to get it to free up the wheels. When I tried with the units reversed (b-a) the light did stay on so I am sure it is a jam of some sort in the drive mechanism.

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
