The Stepchild? Although Strasburg is known as a bastion of steam, there are a few diesels on the roster to handle a little freight on the side. One of the first locomotives acquired by the little road after its rebirth in 1958 was this little 44-tonner from the Pennsy. As she has gotten older and spare parts more scarce, she's been pushed aside by a newer, larger diesel, leaving this center-cab with little to do.
