Uintah 2-6-6-2 vs Mantua 2-6-6-2

[nkp_174]

This is the best I can come up with, based on measurements of the actual Mantua 2-6-6-2, and the HOn3 SVRY 2-6-6-2 (formerly Uintah 2-6-6-2T)
Driver diameter: SVRY 42" Mantua 52"
Wheel base pilot center to trailer center: SVRY 40' Mantua 46'
Heigth, railhead to top of stack: SVRY 14' Mantua 16'
Boiler diameter: SVRY 69" Mantua 73"
Width (cab): SVRY 9'-9" Mantua 10'

In S scale, The Mantua would have:
Driver Dia. 38"
Wheelbase 33'-6"
Boiler Dia. 54"
Height 11'-9"

There is no fixed size ratio between the SVRY/Uintah 2-6-6-2, and the "Standard gauge/Mantua" version.
Hope that helps.

So it is essentially just a caricature of it. Regardless, they are both very nice. 52" drivers seem to be a wise choice since they are typical for a std gauge engine of the time.

Sumpter, thank you very much for providing us with dimensions!
