Vicksburg & Meridian 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class California (Locobase 7950)

Data from CNO&TP 1893 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 2194 and 2196 in January 1873.

This pair of Americans was small even for 1873, especially in such dimensions as overall heating surface and cylinder volume. The V&M named the second engine Texas.

They were considerably smaller than the other 400-series engines on the Alabama & Vicksburg, the others having been delivered more than 15 years later.
