Alco Based Slugs MT6 and MT4

Conrail's yard slugs, the 4 axle MT4 and 6 axle MT6 were rebuild from ALCO units to perform low speed switching duties. Most of the MT4s were retired by the end of Conrail's era, but, after a truck swap, the MT6s served on for their new owners.

CR 6849 AEH12 slug Cleveland 11-79

Conrail slug 6849 resides in the Collinwood deadline this November 1979 day. It's 1/2 of a 2 unit set in which both the mother and slug had the same number. The mother was a former RSD-15 with an EMD engine in it, and the slug was kitbashed from an RSD-5 and RS-1. It would be Conrail's first slug. They were numbered 9949 on the Penn Central, and were renumbered 6899 just prior to scrapping in 1980.

CR 6849 Syracuse, NY 2/12/1978

6849 consisted of an EMD reengined RSD-15 and a converted RSD-5 slug. This is the converted RSD-5 slug.

Selkirk Hump 1990

A mother and slug begin to back down from the crest of the hump at Selkirk yard after releasing the last of their charges at the summit in 1990. The normal slug sets at Selkirk were SD38s and MT6 slugs, so I assume that is what is pictured here.
