OK Chaps. The rollers have arrived and the clicking has been traced to when the wheels cross joins in the rails. I've used insulating joiners, but I've pushed them tightly together, so there shouldn't be an issue.
I haven't started the scenery yet, so once the boards become loaded up they should be deadened.
One thing that has become obvious is that the axle directly below the tower is bent on the P&D replacement truck. The whole back end of the loco moves up and down.
My main worry now is that the replacement Pittman motor makes that classic moaning sound reminiscent of the old DC motors. I was hoping that the flash new ball bearing motor wouldn't do it, but it's the same. The motor on my test board is the old Pittman. It doesn't make that sound when it's out of the loco.
I can get rid of the sound by switching off the BEMF, but as this loco will eventually be driven by a computer, it needs the BEMF to be on.
The decoder is a Loksound L - the same as in the Atlas; which doesn't make that sound.
A bit disappointing.
Cheers
