The USRA light Mallet was a road engine. Compare it to the size of the Mantua and you will find it is larger. Granted the light Mallet got assigned to branch lines as heavier power came available, but it was a road engine.
IIRC, the Mantua's prototype was a three foot gauge engine that they modeled in standard gauge.

"Light" is a relative term when referring to the 2-6-6-2's. I believe that the Bachmann Spectrum is modelled after the C&O Class H6, of which the last 10 were built in 1949. They weighed about 449,000 lbs and had a tractive effort of 77,900 in compound and 98,300 lbs in simple. From MR/Linn Wescott's Cyclopedia Vol 1 Steam Locomotives I understand that the H6's, whether 1920's or 1949's, were not a USRA design, unlike the C&O H5's. Can anyone comment?
