- In my younger days, I had a 4x8 table with an oval using 18" curves. At that
- time I had only Athears engines, FP45, SD9, SD45, and SDP45. I also had GSs
- and Fs units, and a lonely SD24 from Atlas. Needless to say I run mostly the
- Geeps and Fs units than the others. Basically SDs tend to jump the curve
- because it does not have enough swing. This happened occasionally (with my
- SD9 all the time), but enough. I then increased to 20" with curves from
- Tru-Scale and I had no jumping anymore.
-
- Does it mean that 20" is the real minimum radius? No, because each engine
- may differ somewhat on the truck swing. But the majority should. Mine do.
