Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 21, p. 77. Works numbers were 15556-15557 in July 1897.
The Baldwin specs show that these two freight Ten-wheelers were to have been numbered 10-11, connoting their proximity to the four Eight-wheelers supplied by Baldwin just months earlier (Locobase 16233). They were given new numbers by the Detroit Southern
Both locomotives were off the Detroit, Toledo & Ironton roster by 1918.
NB: Locobase estimates the heating surfaces based on the otherwise identical dimensions (down to the 1/4" in tube length) of the Pearl & Leaf River's #8 from 1902 (Locobase 11747).
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 24, p. 264. Works numbers were 23440, 23452 in December 1912; 23517 and 23566-23567 in January 1904.
The December engines were originally intended for the Chicago, Cincinnati & Louisville, but were diverted to the Detroit Southern.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 27, p. 194. Works numbers were 25036-25037 in January 1905 and 25080 in February.
These were duplicates of the earlier batch of five shown in Locobase 12342 rolling on smaller drivers in a purely freight role. Like the others, they retained their road numbers when the DS was reorganized as the Detroit, Toledo & Ironton in 1905.
All served the DT&I until the late 1930s. The 85 and 87 were off the roster by 1937, but the 86 was sold in 1936 to Ohio River Company as their XO-6101. The ORC served a barge terminal at Huntington, WVa. The XO-6101 was still switching in the mid-1950s.

The I Rwy was taken up by the Detroit Southern on 25 September 1902, when the engine was renumbered as 64 . After the DS entered receivership in 1904, the line emerged in 1905 as the Detroit, Toledo & Ironton.
