Assiniboine Park's bright red double-decker bus is getting a test drive today before being launched as a public shuttle on Saturday.

The 1967 bus, which once rolled through the streets of London, England, was donated to the Assiniboine Park Conservancy by retired senator Douglas Everett and his wife Patty, who purchased it shortly after London phased out their fleet of Routemaster buses in 2005.

It will provide a free on-off service and stop at a number of locations throughout the park, including major attractions like the conservatory, pavilion, family centre and zoo entrance.
