Weight of a four wheel locomotive

[PhilP]

Henri,
However you build-up additional weight, remember this is an Otto it is based-on..

Build-up the weight slowly, and make sure the loco/tram will still slip. - Check with a load on the coupler, it does not drag the back-end down, and stall..

When you say that you have taken the traction tyres off, how exactly have you done that? Did you replace the wheels, fill the groove with metal, plastic or whatever?

I simply took off the traction tyre and ran the loco as is. That might be a problem on Peco track as the railhead is narrower (I think).

Hm my wizzy cranks runs sans a tyre with no problems at all.

The donor Otto is sans traction tire anyway...

Did some weighting tonight:



Added up to 1600 grams on traction side...



... resulted in 907 grams on the other end ...

Total weight is now about 2,5 kg. This engine IS a battery conversion candidate... So I’m figuring out what to do as a battery conversion does have huge impact on total weight.

Nevertheless this is a very educative exercise so far!

And there a few more bumbs in the road to get it running smooth... Darn R1’s...

With batteries (and electronics) in the boiler-space, you have to be creative with where you stuff weight..
