What locos can / can't run on 35' minimum radius curves?

What locos can / can't run on 35' minimum radius curves?

I have just completed my garden railway, which includes a circuit of about 750 feet of dual gauge 5" and 7 1/4" gauge, with a minimum curve radius of 35' I currently run a 5" don young Hunslet and a 7 1/4" Milner hunslet. I'm now wondering about building a standard gauge steam, and I was wondering what my 35 foot radius curves might limit me to? For example: could I run a black 5 or a B1? Or a pacific (A3 or Duchess)? Or even a 9F?

The usual thing that seems to limit most Standard Gauge locos is lack of movement on pony trucks. It's easy enough to allow enough axle end-float on the drivers. My current loco build is Prairie configuration but re-designed to go round 30ft rads., so it can be done.

I agree totally with Bob's comment above. At Abbeydale (Sheffield SMEE) we have 30ft min radius. We have had an 8F run here in the past without trouble, but we have also had smaller wheelbase locos that struggled.
