When the Iron Railway went back to Baldwin for a Mogul to supplement the 11 (Locobase 12341), it bought a bigger, more powerful version in every respect.
The I Rwy was bought by the Detroit Southern on 25 September 1902 and the 12 was renumbered 65. The DS entered into receivership in 1904 and emerged in 1905 as the Detroit, Toledo & Ironton.
The DT & I eventually rebuilt the 65 as an 0-6-0 switcher and opreated until sometime in the late 1920s.
The I Rwy was bought by the Detroit Southern on 25 September 1902, when the engine was renumbered as 64. The DS entered into receivership in 1904 and emerged in 1905 as the Detroit, Toledo & Ironton.
The DT & I later gave the 64 the road number 60. The engine was gone from the rolls by 1930.
