History

Revenue service

The engine was built by the Baldwin Locomotive Works in August 1908 for the Grand Trunk Railway as No. 118. The No. 118 was renumbered to No. 1708 in September 1919. In January 1923, the Grand Trunk Railway was merged into the Canadian National Railway. Three months after the creation of Canadian National, No. 1708 was renumbered to No. 7157, a number the locomotive carried until February 1952 when it was renumbered to No. 7240. In 1957, the locomotive received its final CN number as No. 7312. In July 1958, No. 7312 was retired at Stratford, Ontario where it had been working as the shop switcher.

Excursion service

In June 1959, No. 7312 was discovered by Strasburg Rail Road Vice President Bud Swearer who was visiting the CN yard at Stratford. The Strasburg Rail Road had intended to purchase a steam locomotive to power freight and passenger excursions and No. 7312 was of appropriate size for the operation. The Strasburg Rail Road negotiated the CN for the locomotive, which was ultimately purchased by a consortium of Strasburg Rail Road officials. Arriving at Strasburg in June 1960, the locomotive was renumbered to No. 31 and placed into service on September 1, 1960, becoming the first steam locomotive to reenter service in the United States. The locomotive was purchased outright by the Strasburg Rail Road in 1968.

Disposition

No. 7312 continued to remain in service up until October 2009 when it was taken out of service to undergo its heavy, extensive Federal Railroad Administration (FRA) 1,472-day inspection and overhaul.
