Class E-1 (Locobase 1223)

Data from A Catalogue Descriptive of Simple and Compound Locomotives Built by Brooks Locomotive Works (Buffalo, NY: Matthews-Northrup Co, 1899), p 171. 10 additional E-2s were delivered in 1902-1903 with 57" drivers.

Brooks builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004. Works #2962-2966 in May 1898, 3191-3193 in April 1899, and 3494-3497 in April 1900. (E-2s were works #4098-4104 in January 1902

As delivered, E-1s engines had inside Stephenson valve gear and valves, a Belpaire boiler, firebox fitting between the last two pairs of drivers and containing 24 sq ft of arch pipes, a stubby smokebox that ended well short of the leading truck axle, and a flared stack.

They were rebuilt in the 1920s with Walschaerts gear, and extended smokebox and a radial-stay firebox above the drivers. Also the original sand and steam domes changed to a squatter shape and an additional sand dome was added behind the steam dome. The E-2s were not rebuilt and went to the boneyard in 1936-1937; the rebuilt E-1s lasted until 1946-1949.

"Monon" is the common name for the Chicago, Indianopolis, and Louisville Railroad.

Class E-1a - superheated (Locobase 6582)

Data from 1941 C I & L locomotive diagram supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.

The E-1 Twelve-wheelers may well be unique among US locomotives of that rare arrangement in being substantially rebuilt in the 1920s. During the makeover, a larger grate, Walschaert gear, extended smokebox, 11" piston valves, and a radial-stay firebox above the drivers resulted in a much more powerful locomotive.. Also the original sand and steam domes changed to a squatter shape and an additional sand dome was added behind the steam dome.

The rebuilt E-1s lasted until 1946-1949.

Data from 1941 C I&L locomotive diagram supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Brooks builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.

This stubby design was not superheated like the earlier E-1s for some reason and its members were retired in the 1930s.
