The average speed should be close to 40 km/h as this line is entirely grade separated.

Expo Line stops, on average, every 1.45 km [1], while the Millennium Line has an average stopping distance of 1.56 km [1]. Both these lines have a combined average speed of 44 kph [2].
Meanwhile, the Canada Line, which stops ever 1.2 km [1] has an average speed, has achieved an average operation speed of 35 kph [2].
So how can a system of 0.83 km reach an average speed of 40 kph?

Considering its strong connections to the present and future Sytrain network and its very large customer base, ridership would be very high. The Main and Hastings station would be an important component in the rehabilitation of the DTES, as this would accelerate the process. There is an obvious potential for an extension down Arbutus which would service Kerrisdale and Marpole.

I understand this is a fantasy thread, but if we talk about realities, it comes down to cost, and personally, I can't see the justification for such a line to serve areas of Vancouver already with highly accessible and usable transit. Plus, if we talk about the need for a "relief," while the Expo Line between Commercial and the downtown core, the system can still handle current and future usage, not to mention, a RRT (whatever option they choose) along the Broadway corridor, will cause even more service duplications. With proper service optimization on the Expo Line when the Evergreen Line is built out, the system can better handle current and future service ridership projections.
