Dear Bach Man,

I am thinking of adding one of the above to my layout.  I only have diesel at the present.  I only have available 15 degree curves on the track that will be used.  Will a decapod operate efficiently on 15 degree curves?  or is 18 degree the sharpest that will allow smooth operation.

It is also my understanding that a 2-8-2 Mikado will operate on 15 degree curves.

Please advise if I am correct on this assumption for the Mikado
