Hi Simon,
A quick?weigh up?of my PLR stock is as follows:
L&B style Manning Wardle 2-6-2 (scratch built) - 520g
WD Baldwin 4-6-0 - 510g
K1 Garratt 0-4-0 + 0-4-0 - 540g - front engine 240g & rear engine 300g
And for contrast my Scale 7 GWR 2-6-2 prairie is going to be about 1.4kg.
K1 will pull everything I've got, the Baldwin is pretty good and the?Manning Wardle has always been the poorest hauler on the line.
I hope this helps.

Is there a rule of thumb for adding weight to a loco - enough to make the most of its power without adding unnecessary strain?
I'm actually getting close to finishing a loco; the prototype is a petrol-electric bogie unit.
The model is plastic and with one powered bullant unit. Ideally, I'd like it to pull half a dozen wrightlines WDLR wagons which have some rolling resistance as they're mostly from the non-pinpoint bearing era.
Before adding weight the loco is 125g and barely enough mass to avoid wheels pin on its own. I've enough lead prepared to fit the body she'll to bring it up to 350g. I've no shortage of lead and plenty of space.
What's the mass is similar locos out there- could equally be a Garrett, funkey, Fairlie. And if powered on just 1 bogie, how is the weight distributed?
Cheers
Simon
