Tight curve

General Discussion
#1

I built a small trolley on an eggliner motorblock . Has anyone tried how tight a curve it will run on?

#2

Vic Smith has proven, that less than two foot diameter is possible.

i have tried out, that 4 wheel locos, with a distance of no more than 80mm/3" between axles can easily run on diameters of 90mm less than (LGB) R1.

#3

Aristo-craft sold two different “pre-made” circles of track, one 32" in diameter, and one 21" in diameter… the eggliner has been demonstrated to run on both.

So the Aristo-craft eggliner will run on at least a 21" diameter circle if not smaller.

I think I will have some fun with this trolley track. Maybe I can get some 40 foot LGB freight cars to run on some of these tight curves!

NOW you are pushing it! (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-tongue-out.gif)

While 40 foot cars can go around very tight curves, it is the coupler that swings outside the curve and derails itself or the car it is connected to.

I have this issue with the LGB genesis on R1 curves, freight cars derail behind it.

#7

I never tried passenger cars.

#8

Truck mounted couplers will help, modifying the undercarriage to allow them to swing, but long cars will inherently try to “stringline” on tight curves.

The definition of “long cars” varies directly with how tight your curves are.
