Canadian National Class Z-1-a
The Canadian National Class Z-1-a was 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.[1]

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. They were very similar to 6 units built for the Butte, Anaconda and Pacific Railway, as was the electrification system. 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) .[1]
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.[1] Another, CN 6712, was donated to the Town of Mount Royal, and was stored at that city's municipal garage pending selection of a suitable display site. Such a site was never found; the unit was cannibalized and scrapped in 2011.
