It was nice to see these things still floatin' around.  ONT 4521 is photographed on Cochrane Yard's Number 1 Track August 11, 2000. Her next stop is the loading ramps to carry new culverts north to Moosonee. These cars were built by Marine Industries with ONR being the proud owner of 25 of them numbered between ONT 4510 to ONT 4534.
