I grew up a half mile from the CN Rail Yards at Port Mann in Surrey BC. We could hear the activities that were taking place there all hours of the day and night which inevitably created a curiosity of all things relating to transportation. I often wondered what was in those cars. Where they came from, and where bound for. Even though being a railroader was not to be, the lure of hauling loads was never far away. In 1973 I became a truck driver for a local delivery service where I one day ended up in those same Port Mann yards unloading a half carload of heating supplies. Now I knew where “this boxcar“ came from and even where it was going.
