Detroit & Lima Northern / Detroit, Toledo & Ironton 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 16 (Locobase 12344)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 53, pp. 249-250 Works number was 41653 in August 1914..

Built for the Midland Pennsylvania, this Eight-wheeler was repossessed by Baldwin and sold to the DT & I. That railroad used the 16 on its Toledo-Detroit Railroad subsidiary.

In 1928 the DT & I donated the 16 to Henry Ford's Edison Institute in Dearborn, where it remained on display for decades. In 1980, the Ford Museum traded the 16 to the Illinois Railway Museum

Class 6 (Locobase 16233)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 21, p. 14. Works numbers were 15316-15319 in May 1897.

The D&LN was originally chartered as the Lima Northern on 27 March 1895 and opened its first 80 miles of line from Lima to Adrian, Mich and soon extended it to Detroit. It was reorganized as the D&LN very soon aftrward, which then combined with Michigan division of the Cincinnati, Jackson & Mackinaw to be called the Detroit, Milwaukee & Toledo.

Although building continued and the railroad acquired the Ohio Southern, contractors' suits and an outstanding Ohio Northwestern tab of $18,750 owed to Schenectady for eight locomotives forced the D&LN's foreclosure late in 1897. Again reorganized as the Detroit Southern, the line emerged from bankruptcy in May 1901. Further rearrangement, sale, and stock swaps resulted in the creation of the Detroit, Toledo & Ironton in 1905.

Three of the four were scrapped in 1921, but number 7 did not run from the time it was idled at the Ford Company's River Rouge plant until its complete restoration by the Henry Ford Museum. Its initial 21st century run occurred on 12 June 2013.
