- Baldwin Bulletin 193 calls this a ... "road transfer locomotive" - if powered by an 8VO engine the four exhaust stacks places the design to after the War Production Board restrictions were lifted in 1944 |
- c/n 72235, class DS-4-4-1000/1 NA 551 (1000hp switcher class)
- abandoned, likely due to the introduction of the 600 series engine and DS locomotive models
- first light road switcher, the DRS6-4-660, produced in 1946, was for export only
- first domestic 1000hp light road switcher, the DRS4-4-1000, was produced in 1948
