Running problems
I know this loco has been 'out' for some years , however, I have only just got hold of one and am rather disappointed in its running qualities, it stalls on any dead frog point and it seems to slip very readily when hauling anything more than 3/4 wagons, interestingly it finds difficulty in hauling 2 Maunsell coaches but propels them with no problems. I think it may be that when hauling the weight on the coupling lifts the fron of the loco enough to make it just grip on the rear 2 drivers whilst when propelling the weight pushes the loco down onto all four wheels. This may be an old topic which I can't find here for which I apologise but has anyone else had this problem in the past and maybe has a cure?

Not familiar with this loco, I've pulled up some details and see it is designed with a space in the smokebox for a decoder. Are you running on DC or DCC? If DC, you might try some additional weight in the smokebox to keep the front drivers on the track to increase traction. Ther smokebox door is held on by magnets and pops off to facilitate access KMRC Locomotive - LSWR Beattie Well Tanks
Hope this is of some help, but if not, the next bus should be along in a moment!
Best,

At 6'4'', Bill is a tall chap, then again, when horizontal he is rather long and people often used to trip over him! . . . and so a nickname was born :)

Someone with prototype knowledge perhaps can better answer this but from memory i think you need to look at what the Well tanks actually hauled in real life i believe it was only capable of light loads and perhaps 2 maunsells is more than the prototype would have pulled.
Hopefully someone with prototype knowledge can elaborate on this.

Still a valid question though and I'm looking forward to a good solution.

This particular model did win awards if it were not felt near to the prototype pulling wise these awards would not have been forthcoming.

The Beattie Well Tanks could pull a reasonable load, as they were suburban passenger engines in their earliest days, albeit in a considerably different form. The models represent them in rebuilt form, where they were exiled to the far west and hauled mainly goods traffic.

It now pulls what I'd call a prototypical load… half a dozen wagons or a couple of coaches. I fitted Kadees to mine so that negates the coupling causing the problems you describe. I fitted sound to mine and it sounds the part, even though I've never actually heard the real one.
Cheers Pete.

These locos were not built nor designed to haul anything more than very modest loads in real life and this is replicated in model form. Mine happily cope with two carriages or around ten short-wheelbase freight wagons on the level though will slip if they are asked to tackle a (typically steep) model gradient with that much.
I have not had a problem with them stalling other than momentarily on less-than-clean rails or with wheels which, upon inspection, are less than clean. A spot of routine housekeeping and all has been well.
It is possible to add a little weight as Jeff says even with a decoder inside the boiler. This may improve running but don't overdo it as these are tiny locos and adding excessive weight will stress the motors.
The problem described might also be cause or contributed to by uneven track or imbalance of the loco caused by "picking up her skirt" - railwayese for the front wheels lifting from the rails when too much weight is coupled to the drawbar and an attempt made to start. The fact that the loco in question performs better pushing than pulling suggests this latter might be the case. Check the rolling resistance of the train - it isn't always weight alone causing the problem; a stiff wheelset might be contributing to it and / or curve radius causing drag could also be a contributory factor.
My layout has had Peco code 100 insulfrog points throughout and Jeff has seen it - and the well tanks - in operation so might recall that they ran without problems with the exception of up an unrealistic gradient.
