Cumberland & Pennsylvania 2-8-0 "Consolidation" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 27 / C13 (Locobase 12647)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 22, p. 245. Works numbers were 27066-27067 in December 1905 and 29578 in November 1906.

A little more than a decade after they went to work for this Pennsylvania shortline, all three were sold to the Hocking Valley as their 280-282.

See Locobase


Class K (Locobase 6570)

Data from 1936 C & P locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

The C & P was a short line in Maryland's Allegany County that moved coal to the Mt Savage junction with the Baltimore & Ohio. Patrick Stakem of the Western Maryland Historical Society writes that this small railroad established a competent locomotive-building facility at its roundhouse in Mt Savage, Maryland.

Stakem's account shows that this unusual capability resulted from the arrival of James Milholland as director of the locomotive shop. Milholland was even then a well-known locomotive superintendent who had worked on the Philadelphia & Reading. The C & P shops took on several rebuilding projects before offering a catalogue of new locomotives for the railroad and for export.

At the turn of the century, Mt Savage supplied two classes of Consolidations for the C & P. This trio represented the smaller design; the Ls (see Locobase 6571) the larger.

It eventually came under the control of the Western Maryland and the shops were closed.


Class L (Locobase 6571)

Data from 1936 C & P locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

The C & P was a short line in western Pennsylvania that had its roundhouse in Mt Savage, Maryland; see Locobase 6570 for a more complete history. The L series seems to have been an enlargement of the two Ks that were delivered 5 years earlier, although the firebox heating surface remained about the same.
