The Successor to the Mark I SkyTrain
After SkyTrain was extended to Scott Road in 1991 and plans were put in place to extend it to the Expo Line’s current terminus, King George, there was a lot of talk by BC Transit and the then ruling Social Credit (Socred) government of the time on where to take Metro Vancouver’s transit network next. With more service means more trains and BC Transit made it a point to investigate its options.
Test Vehicle 06 or “TV06” was brought over from Urban Transportation Development Corporation’s facility in Kingston, Ontario. UTDC were the creators of the original SkyTrain technology and vehicles, so it was a natural fit for them to be involved with the creation of a successor vehicle.
UTDC’s approach was simple: take an existing Mark I vehicle and extend it. What was interesting about their approach was that the vehicle they chose was used on the SkyTrain demonstration line in 1983.
The vehicles used for the demonstration were the property of UTDC and had been used for testing and sales purposes after they returned home. UTDC decided that one of the vehicles would be better served as a test platform for a longer version of the vehicle with an additional door.
BC Transit continued to investigate options for the future of SkyTrain including hiring a film production crew to build a mockup train. This train was made of wood and while I cannot confirm, I have read that it was put on display at the 1991 Pacific National Exhibition (PNE).
These trains may look familiar despite never having made any revenue service appearance, as this version of the Mark II was eventually used for Kuala Lumpur’s metro system. They were sold as cheaper than existing SkyTrain vehicles, could hold twice as many people per car, and were of course still compatible with the existing system.
However, plans were about to briefly change with an upcoming election. The sitting Socred government lost handily to the New Democratic Party (NDP) in the 1991 fall election. This new government had long been skeptical of SkyTrain and wanted to implement light rail (LRT) as opposed to advanced light rail (ALRT).
The story around the Millennium Line potentially becoming LRT too deserves its own article, but suffice to say, after a few years, this idea was abandoned sometime after Premier Mike Harcourt resigned and Glen Clark took his place.
He favoured going back to SkyTrain and in 1998, his government had BC Transit partner with Bombardier, UTDC’s successor to not only use ALRT technology for the new line, but to also build the trains right next to SkyTrain’s maintenance facility in Burnaby.
A “dummy” train was made and tested on the Expo Line during the planning stages for the new vehicles. It had no powertrain and thus had to be pushed around, but it was used to provide data to BC Transit and Bombardier for the development of a new train.
In 2000, the Mark II test vehicle started to venture on the now Expo Line. For the most part, tests were flawless and minus a few tweaks to the line itself such as changes to switches or placement of track indicators, they eventually entered revenue service in 2001 just in time for 2002’s opening of the Millennium Line.
The Mark IIs and Mark Is were a common sight on both lines. However, the Mark IIs were more popular as they had features such as air conditioning and were considerably quieter in operation. Exiting a Mark II train during the morning or afternoon rush was also much easier thanks to having three doors and more space when standing.
While the Mark I is still a common sight on the Expo Line, they are approaching nearly four decades in use for the original train sets and despite a refurbishment programme starting in 2013, they are due to be retired.
Later this year, Mark V trains will be delivered from Alstom, who has since acquired Bombardier. A total of 41 new train sets have been ordered to replace the aging Mark I fleet and to allow for the extension of the Millennium Line to Arbutus to meet expected capacity needs. By 2026, these new trains will completely replace the Mark Is.
I personally hope someone acquires one of the Mark I pairs and opens a coffee shop inside of one called the “Expresso Line”. If you like that idea and want to run with it, it’s free.
