I used that alternative... on the 2nd and 4th drivers as stated above. Hard to get a 7 1/2" gauge locomotive with a 36" rigid wheelbase to turn a curve very well. She does pretty good, though. About 50 ft, or just under it, is the sharpest radius I've ever been around. It made it ok.

Isn’t the real problem not too sharp a radius in this case but kinked rail at a joint?

If this is the only spot it happens I’d fix the track first.

Just my two cents.

wow 36 inch rigid wheelbase is extremely long. Even a Texas & pacific 2-10-4 w 63 inch / 8 3/8inch drivers had a 22 FT driver wheel base which would translate to 33 inches in 1.5 scale.

I would add, the only section that should only come into play is the wheel base between 2 and 4. my ten wheeler has a 20 inch wheel base between 1 and 3 with #2 being blind,, but i am also wondering about the width of the tires currently.
the more i think about it, the more i am thinking my tires are already wider then "normal", not just the blind one..
If it is not live steam. its not worth it.
