A Baldwin-built 0-6-0 steam locomotive is expected to begin operating at Steamtown National Historic Site by Aug. 25.
Once No. 26 is fully operational it will pull the park’s yard shuttles.
The date that service is expected to begin will coincide with the 99th anniversary of the founding of the National Park Service.
No. 26 will be the first steam locomotive to operate at Steamtown since 2012.
The rebuilt locomotive passed a full-scale pressure test last December and Federal Railroad Administration inspectors allowed Steamtown to operate the Baldwin after another trial in the spring.
The locomotive, which will have a green livery, still must complete shakedown runs in the Steamtown yard.
Supervising exhibit specialist Barbara Klobucar said Steamtown discovered that olive drab green was the locomotive’s original color.
No. 26 was built by Baldwin in 1929 and used as a switcher at Baldwin’s Eddystone Plant until it was sold in 1948 to Jackson Iron & Steel of Jackson, Ohio.
There it switched cars at the plant and to interchanges with the Baltimore & Ohio and the Detroit, Toledo & Ironton railroads.
Sold in 1979 to a private owner, it remained in Jackson until June 1983, when it moved to Grand Rapids, Ohio.
Then it transferred to the Mad River & NKP Museum in Bellevue where it sat until 1986 when it was acquired by the former Steamtown Foundation in trade for Canadian National 4-6-0 No. 1551. It arrived in Scranton, Pennsylvania, the home of Steamtown, in January 1990.
“All of the railfans are just champing at the bit,” Dawn Mach, Steamtown assistant superintendent, said of the long-awaited return of the engine to service. “People are excited, especially since we are starting to wrap up the work.”
