Hi Tony,Why would the weight need reducing, Mike?
2kg does seem excessive.
I suppose the proof of the pudding would be to load it until it wheel slips. If it’ll pull a prototypical train, it’ll do.
My guess is that at 2kg, it might simply stall, which does no good to the model, or the power supply.



The large prairie has now been re numbered to 6144, one of the class that carried unlined green livery, seen here having been turned ready for its next turn of duty
A very nice looking loco. I have mine numbered 6148 as operating on the North Somerset branch. A pity that I have it in black, I think it should be green, but not sure whether it should also be lined. Hey ho!
The photo of 5802 at Barmouth show the toolbox towards front of splasher, as per your original model.For those who prefer to see locos in a pristine state (and I believe there are some) look now as it won't be seen again this like this!
My plan is to model 5802 as it would have appeared around 1958, just before withdrawal, still in GWR livery with B.R. smokebox plate.
Work has begun today by removing the shirtbutton emblem, re siting the RHS toolbox to the centre of the splasher, removing the conduit running up the cabside and the twin battery boxes, which I will replace with a single one.

These toolboxes seem to have been moved about a bit, probably ďuring works visits. Early photos of 5802 show the rh toolbox in the forward position, whereas later photos show it in the centre.
