Chicago & Eastern Illinois 2-4-4 Type Locomotives

Class Details by Steve Llanso

Class 50 (Locobase 7121)

Data from C&EI 6 - 1904 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 3501-3502 in June 1891.

The second set of commuter tanks resembled the first batch, but came from Schenectady. Like the first group, the design had the firebox was suspended behind the last axle. They also show three equal-sized domes, two sand domes flanking the single steam dome.

Both of these were sold for scrap, 50 in September 1906, 51 in February 1907.

Class 62 (Locobase 7122)

Data from C&EI 6 - 1904 locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 1703-1706 in February 1887.

Like other Chicago-area railroads of the time, the C & EI competed enthusiastically for the area's growing commuter traffic. And like the others, the railroad adopted wheel arrangements suitable for double-ended running. The first quartet were these tanks, which were actually rather large for the wheel arrangement. The firebox was suspended behind the last axle. They also show three equal-sized domes, two sand domes flanking the single steam dome.

They were sold for scrap in 1906-1907.
