Trainbuilder N class on the bench.

I purchased this Trainbuilder N class oil burning steam locomotive, N 431, back in September 2020 and then it was sent to me via DCCSound to have a LokSound V5.0 micro decoder and speaker installed in the tender. It has been stored since that time, but now with a functional work bench setup in the layout shed I have finally been able to get the loco active and do some decoder and running tests on the rolling road.
I did my usual things like quieten down the sound a little and also dim the lights right down.

And then the lights dulled down with setting them via JMRI and the function outputs with a value of 3. And the rear head and marker lights below, got the same treatment.


N 431 running at speed on the rolling road under test. I had to take the brake rigging off and adjust some of the 'pads' as they could contact the wheels and cause very rapid shorts. I thought I had some images of the brake rigging removed, but I cannot find them now. Here is a still from a video showing the area that was shorting.


Now this was not happening all the time, just erratic enough to be a nuisance. Anyhow, removing the brake rigging and giving it a slight adjustment before refitting has eliminated this issue now. So, below is a photo and then a video of the motion running on the rolling road now fully spark free!
