The Radium Express is a Russel Brothers[1] tugboat operated by the Northern Transportation Company.

[2][3][4] The vessel was built in Owen Sound, Ontario, disassembled, and then shipped by rail to Waterways, Alberta, which was then the terminus of the North American railway grid.

[6] The Canadian Transportation Agency reported her speed as 9 knots (17 km/h; 10 mph) in 2011.

[5] The account said the winching was complicated because permafrost caused the trees to which she tied her winch-line had shallow roots.

In 2005 Atomic Energy of Canada published a study of the toxic legacy of the mining of radioactive ore at Port Radium.
