Philadelphia & Reading 0-6-0 Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Philadelphia (Locobase 2547)

Rebuilt from the Richmond, which blew up 19 days after it entered service on the Reading in September 1844. The incident, blamed by one authority on a lightning strike, was later more plausibly attributed to defective feed-water pumps leading to low water over the crown sheet. The Philadelphia, which drove on the rear axle rather than on the middle one as had Richmond, was turned out by noted designer James Milholland. In addition to the 2" tubes shown, the boiler also held four 1 3/4" tubes.
