NB Southern has purchased four CN slugs. The four are CN 251, CN 269, CN 501 and CN 508. Two are currently in Winnipeg (CN 269 and CN 501) and the other two are in Edmonton.
The four were part of a long list of units for sale on CN's web site this summer.
A little history of these units:
- CN 251 was converted from a GP9 in 1990.
- CN 269 was converted from an MLW S3 in 1991.
- CN 501 and CN 508 were purpose-built as slugs in 1978 as CN 261 and CN 268 and were renumbered in 1990.
I understand the four slugs needed some work before they were road-worthy. I don't know when they will be heading east but I expect it won't be too long.
Personally, I've only seen CN 501 (my picture above), both times working the hump at Symington Yard here in Winnipeg. Two 5xx slugs are paired with two GP38s to work the hump yard. The 2xx units are usually paired with a GP9 or GP38 and work industries, as far as I have seen.
