Old Colony 4-4-0 "American" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 132/C-2 (Locobase 16312)

Data from "Passenger Locomotive, Old Colony Railroad", Railroad Gazette, Volume 19 (25 February 1887), pp. 125-127.

By 1900, the quartet of locomotives had their driver diameters reduced by 3" (76.2 mm) to 66" (1,676 mm).

1700, 1699 were retired in February 1917 and 1698, 1701 stayed in service until June 1923.


Class 256 / C-2 (Locobase 14734)

Data from James Dredge, A Record of the Transportation Exhibits at the World's Columbian Exposition of 1893 (New York: John Wiley & Sons, 1894), pp. 241+.

It's not clear why Old Colony Railroad thought it necessary to send this engine to the 1893 Columbian Exposition in Chicago. It wasn't unusual in its size or capability--hundreds, even thousands like it were in service across North America. So we can view it as representative of one of the most widely distributed designs in the steam locomotive era--a North American Eight-wheeler.

The engine was shown just as the New York, New Haven and Hartford Railroad took out a 99-year lease on the entire system of 617 route miles (993 km) throughout eastern Massachusetts. As a result, the New Haven completed its shore route between New York City and Boston.

At that point, the 256 and several of her sisters were lumped together with a variety of other acquisitions as class C-2. Of that variegated class, approximately twenty had been built in the Old Colony's shops.
