In 1992-1994, CN reporting marks replaced Duluth, Winnipeg & Pacific reporting marks on some cars from the DWC 607900-608999 series - 750 cars originally built by Marine Industries Ltd in 1970 for lumber service. Special bunks were added to these lumber cars to accommodate aluminum ingots. Renumbering put these cars into the CN 610400-610479 series. CN 610433-610469 are empty in Quebec (top Gerry Burridge photo purchased September, 1998).

Doug Stark posted this nice overhead view on Facebook, showing CN 610449 at Burlington ON in June, 2002. This photo also shows the 24 side- and 12 centre-stake pockets, the former apparently removed. Notice also the open car floor in the area of the bunks, perhaps to reduce weight since this area was not needed for the precious shiny lading they carried. Some cars had brown-painted, not green-painted bunks.
Chris Wright posted a 1990's photo on Facebook, taken at Niagara Falls, of CN 610440 with an ingot load.
Perhaps this creative re-use of displaced bulkhead flat cars was thrifty Canadian ingenuity at its finest. But in our throw-away, just-get-something-new world, new-built cars with more capacity were on the horizon to handle loads such as these.
The November 1991 issue of TRAINS Magazine included two Pete Swanson photos taken in Rochester, NY. Both show Conrail train SETO (Selkirk NY to Toledo OH) and lo and behold...the bottom photo includes three loaded CN ingot bulkhead flatcars, plus one ingot-carrying CN flatcar. So, having saved this page until now, I guess it could be said this post was 25 years in the making!
I'm generally a fair-weather photographer. Two Sundays ago I was confronted with CN No 376 - in a downpour near Mi 179 Kingston Sub. Conflicted, there was one of those over-lettered Sullivan Holyoke scrap hoppers and some GATX WRWK nicely-repainted boxcars! Quick, roll down the window! Shower-shoot! Digital drizzle!
B.T.S. can stand for two things: Bed Time Snack or Back To School. The latter is being celebrated by a welcoming committee of Queen's University students at Kingston's Outer Station. Undated. (The photo, not the students. Some of them probably dated.)
