Toledo, St Louis & Western 4-4-2 "Atlantic" Type Locomotives

Class C / E 3 (Locobase 6584)

Data from T, St L & W's 1911 and 1924 locomotive diagram books supplied in May 2005 by Allen Stanley from his extensive collection.

Known as the Clover Leaf, this railroad always skated close to the financial brink (see Locobase 2517). But it had grand enough pretensions to jump on the Atlantic bandwagon. This Brooks pair cost the line $16,750 each in 1904, according to the 1924 book. They were calculated to develop 1,202 HP in the cylinders and 1,090 from the boiler's measurements.

The Nickel Plate snapped up the Clover Leaf in 1923, at which point the two 4-4-2s had 7s added to their numbers. Retirement came in 1933.
