Largest steam locomotives to operate in New England were the ten T-3-a class 2-10-4s of the Central Vermont Railway, formally part of the Canadian National Railways system through stock ownership. They were erected by the American Locomotive Company in 1930, and at 419,000 pounds were the lightest Texas type locomotives built for a North American railroad. Nevertheless they were reputed to be hard on the CV infrastructure when running at speed, and the bane of track maintenance crews. They had low 60-inch drivers, 27x32-inch cylinders, and a boiler pressure of 250 p.s.i. (For other specifications consult the commentary for No. 707, following.) Above we see No. 705 as captured on film by H. W. Pontin, owner of the Rail Photo Service of Boston. This engine features a web-spoked main driver applied in a later shopping, perhaps in an attempt to reduce pounding on the railhead.
