Re: Scale Weights


Tim O'Connor
 

Paul, model trains do not perform like real trains.
For one example, the weight of the car on the rail
is distributed over an area larger by a factor of 87.1.
(The surface area of contact between the wheel and
rail only changes in 2 dimensions as you scale down.)
Also, our curvature is usually about 10 times as sharp
as you'd find on a prototype. If you put 1 oz cars with
5 oz cars in a train and run it up a 3% grade with 40
degree curves, then don't be surprised when you get
"stringlining" of cars in the middle of the train.

There must be a FAQ out there somewhere... try the
LDSIG mailing list.
