Hi Chris,

That would make an interesting project. A 2-10-0 should be no more
difficult than any other loco apart from all those knuckle joints on
the coupling rods ( ugh!) and the need for very accurate wheel
quartering. I've just got a set of plans for 'Austere Ada' and am
thinking of possibly making the 2-10-0 version. Plenty of traction
with all those driving wheels!. It may be worth considering removing
the flanges from the middle set of drivers as done on the full size
9F's etc. which will help with tight curves. I think LBSC recommended
this for the 2-10-0 version of Austere Ada. His 2-12-0 caterpillar had
no flanges on the middle two sets of drivers. The boiler barrel will
also be very long on such a loco so will probably need a combustion
chamber on the firebox to keep the tube length short.

There doesn't seem to be a lot of information on the minimum radius
that various loco's will negotiate but most society tracks in the UK
are multi-gauge and cater for up to 5" gauge loco's. Obviously the
minimum radius has to cater for the 5" loco's so there will be no
problem for a 2 1/2" gauge.
