Philadelphia & Reading class A-4

Since the Philadelphia & Reading had access to anthracite culm as cheap fuel, switchers were also built as Camelbacks with Wootten fireboxes. This included the class A-4, which had a 0-4-0 wheel arrangement and was built a total of 19 times in 1902 and 1903. They were modernized between 1905 and 1907 with higher boiler pressure and a larger tender.

Only number 1187 has survived, which was sold to the E&G Brooke Iron Company in 1946 and was in use there until 1962. It was now purchased by the Strasburg Railroad and was used there on short runs in front of passenger trains. However, since the locomotive did not produce enough steam for line service, it was retired in 1967. In 2020 it was purchased by the Age of Steam Roundhouse and is being cosmetically restored there.
