Caption: The Ottawa Central acquired CN trackage between Ottawa and Pembroke, Ontario, on their truncated mainline to Capreol. The agreement also included trackage rights on VIA Rail between Coteau and Ottawa. The OCRR began operations on Thursday, December 31, 1998, and continued for almost ten years until Monday, November 8, 2008, when Canadian National repurchased the assets from the Ottawa Central's owner, the Quebec Railway Corp. The Ottawa Central also contracted with the Ottawa - Carleton Regional Municipality to operate the former CN line to Arnprior. Ironically, CN is now discontinuing service on these lines, and the future of the Arnprior line is uncertain.

It is on the latter line where I caught the westbound local to Arnprior at South March, Mileage 5.5 of the former Renfrew Sub, at 925 on Wednesday, May 5, 2004. RS-18u 1834 wears the New Brunswick East Coast name as it served for a time on that subsidiary of the Quebec Railway Corp.

The CPR acquired RS-18 8776 from MLW in May 1958 (Serial 82457), upgraded it in June 1985, and renumbered it 1834. CP Rail sold the unit to the NBEC in April 1998, who later leased it to the Ottawa Central. CN acquired the RS-18u with the repurchase in 2008 and retired it the same year.
