What is your adverage pull for a Mikado or the Decopods???
Tractive efforts for 2-10-0’s in the USA ranged from around 40,000 lbs for the “Russian” like the HO scale Spectrum model to over 90,000 lbs for the PRR I1 and WM big ones.
USA Mikado’s ranged from around 20,000 lbs for DRG&W 's little narrow gauge to over 60,000 lbs for PRR L1 and the USRA Heavy.
These are approximate ranges.
I think was talking about models Nigel.
if you are talking models take a look at this site, scroll down to the bottom, there is a
listing of the pulling power of various HO locomotives
