I forgot to say that the track is clean and the wheels are clean and in a straight line it will pull anything, but up the top of the incline on a corner is the problem.

BRAWA 06 with no grip
Dear All,
It took awhile to get my Liliput BR45 going, once it was run it it performed OK would pull 18 plus wagons, my ROCO 03 would pull about the same or a few more, so then I tried my BRAWA 06 and what a surprise, with only 5 wagons it slipped at a certian point on the track every time, the best that it would do was 3 wagons and even then it still started to slip, as the drive is from the Loco wheels and it is quite heavy I could not believe it, also the radii of the track at that point is quite large although it is on a curve
Another modeller suggested that the axels might be not all together or something like that, it is brand new out of the box but did come from overseas, I was just wondering if anything might have happened to it that would make it do what I have described.
Regards
Anthony

Hi Anthony,
has a traction tyre come off?
Otherwise it sounds similar to the issue I had with my BR05 which Richard Johnson looked at. This turned out to be an issue with track voltage.
cheers Neil

Hi Antony,
Have you looked where it is losing traction and are the transition areas flat enough to keep all wheels on the track or are some wheels losing contact at the stalling points?
Cheers

You are in possession of the key facts to solve this problem with this statement. Nothing fundamentally wrong with the loco. But it looses traction on a track section with a transition in two planes. There are two approaches to fixing this.
If entirely happy with the layout, and particularly if you don't want to modify the track in any way, then you will have to look at making the loco flexible enough to keep the weight on its' driven wheels (or if it is traction tyred, on the rubber tyres) through the trouble spot. Basically what will be happening is that carrying wheels on the loco, (and quite possibly the tender too) are carrying much of the loco weight at this location. Compare the flexibility of the most similar loco that operates satisfactorily on this section, with that of the 06; and modify to make it as similar as possible, until you get the required result.
Alternatively ease either or both of curvature and gradient transition, and if possible have the gradient transition occur on a straight section rather than the curve. (That would be my choice as it will likely improve both weight haulage capability and running reliability for everything you operate.)
Or do both, to whatever extent necessary for a satisfactory result!

Dear All,
I will be on holidays for two weeks, when I get back I will do a lot of tests after the postings here and report back, I have also discussed this with Neil Woods as wellas he has the same Loco.
