NB Southern Railway Rolling Stock 1

The green CRLE boxcars are a common sight in Saint John.
However, this is the first one I've seen lettered for NB Southern.
This was spotted on the CN local heading to Irving Paper.

Two maintenance-of-way boxcars (right is #403383) by the Fredericton Junction station (formerly VIA).
Note the platform on the top of one of the boxcars.
I have seen this boxcar used to repair the Reversing Falls railway bridge in Saint John.

A different view of the same cars.

Note that NBSR 403383 (the closer boxcar) is now
permanently stationed at Fredericton Junction.
When the yard was removed, a short section of track and 403383 were left there.
