Texas Mexican Railway No. 510
Baldwin DS44-750 Switcher built 1949

The Texas Mexican Railway, which runs between Laredo and Corpus Christi, was the first “Class 1” railroad to completely replace its steam engines with diesel locomotives. No. 510 was in the second wave of new diesels that displaced steam on the Tex-Mex’s lines.

In the photo above, museum volunteers have almost completed the repainting of No. 510 into her original Tex-Mex green and orange colors.  No. 510 was built in Eddystone, Pennsylvania, by the Baldwin Locomotive Works.  Texas Mexican used the 750-hp locomotive for switching chores at its various rail yards.  However, No. 510 is more than just another switch engine – she is a movie star!  The engine was assigned the task of pulling a train over Jack Nicholson in the film The Border, shot partially in one of the Tex-Mex’s yards.

In the mid-1970s, No. 510 was sold to the Texas Crushed Stone Co. (TCS) of Georgetown, Texas.  The locomotive operated in the TCS gravel yard in Houston, hauling uncounted tons of rock destined for use in building Houston’s freeways.  In 1984, a newer locomotive took over duties at the gravel yard, and No. 510 was set aside as a spare.  By 1989, No. 510 had become surplus to TCS’ needs, and upon donation, the 198,200-lb engine became the first locomotive acquired by the Gulf Coast Chapter – NRHS.
