The Vancouver area is served by three heavily patronized
urban rail lines on a system known as SkyTrain. The original route,
now expanded and called the Expo Line, travels together with the much newer Millennium
for fourteen stations outbound from Waterfront in downtown Vancouver. The
Expo Line then goes across the Fraser River into Surrey, and the Millennium loops
back through Burnaby on a different route from what it has traveled earlier, returning toward central
Vancouver (but not to downtown).
Much of the original route is above-ground, as indicated by the system's common
name. The newer Canada Line has a long subway portion, extending far
south under and beyond downtown, and through most of its Vancouver run,
before it reaches the surface and aerial running to split in Richmond for two branches.
SkyTrain is an operating entity of TransLink, which is the name given to the
variety of services under the purview of the South Coast British Columbia
shows a two-car train heading away from the skyline of center city, east of the Main
Street-Science World Station, on the original right of way.
