Works number was 16903-16904 in July 1899, 18078 in August 1900, and 18084 in September.
The D & M took its name in 1894 following a reorganization of the bankrupt Detroit, Bay City & Alpena. Starting from Bay City at the curve of the thumb, the line followed the Lake Huron coastline 131 miles north to Alpena. A year later, the D & M took over the Alpena & Northern which extended the coastal route another 65 miles to Cheboygan.
Photographs show an upright, relatively short-coupled design. Although 6 locomotives of essentially identical design formed the class,, wheel diameter separates this mixed-traffic quartet from the frankly freight pair in Locobase 12354.
131, 134-135 later operated on the Detroit, Caro & Sandusky as 17 and 134-135. The DC & S represented a 1925 re-organization of the bankrupt Detroit, Bay City & Western and extended southeast from Bay City to Fargo. (The DC & S didn't have the money to rebuild the wooden trestle over Mill Creek south of

See Locobase 12353 for a history of the D & M and the Detroit, Caro &
Southern. Built to the same design as the previous 4 Ten-wheelers, this pair had much smaller drivers and were thus dedicated to freight service.
135 later was sold to the DC & S, but retained its number.
