The CN Boxcab Electrics were a series of six electric locomotives built by General Electric for the Canadian Northern Railway in 1917. They were used in service through the Mount Royal Tunnel in Montreal until retirement in 1995, operating for 76 years, 7 months and 12 days.
They were classified as a Box-Cab model 0440-E-166-4-GE-228-A by General Electric, delivered new to the Canadian Northern Railway. Each unit weighed 174,000 lb (79,000 kg). They had a B+B wheel arrangement, a maximum continuous tractive effort of 19,600 lbf (87 kN), capable of operating at a maximum safe speed of 55 mph (89 km/h) .
They were given the following classification: Class: Z-1-a by the CNoR in 1919; CN continued to use the same classification after 1919. One unit, CN 6713, was retired in 1993 and was then cannibalized for spare parts to supply the remaining class Z-1-a locomotives.
