Data from the C&EI 6 - 1904 Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 2832-2837 in May 1889.
These must not have suited the D&IR's requirements very well because they were sold to the Chicago & Eastern Illinois in April 1892. See Locobase 7129.
