Built in 1962 using the frame and other components from Alco S1 #102. The slug was modified in 1967 by replacing the original Alco Blunt trucks with AAR Type A “GSC” trucks removed from WM #130 a Baldwin VO1000.
138-T spent most if not all of its working life in the Hagerstown yard mated to one of the BL-2s, normally WM #81. Eventually 138-T was donated to the B&O Railroad Museum in Baltimore, MD in 1986.
The appearance of 138-T changed slightly over the years besides the truck change in 1967. Earlier versions do not have the traction motor blower inlet screens they were added sometime in late 1977-early 1978. Footboards were forbidden by the FRA after September 1978, but there is photographic evidence that 138-T still had her footboards as late as July 1979. If you photos to document this please contact me.
The model reflects all changes to 138-T up to retirement. If there is enough interest in the “as built” version I am amiable to producing it.
