Toll port

The Toll port was an intergalactic way station. The Doctor and Mel were the 10 billionth customer, they landed at port G715. As a prize they received a fabulous 50s tour to Disneyland on Earth with Nostalgia Tours. The Chimeron, Delta landed at the port and boarded the tour bus. She was followed by the Bannermen who killed the Tollmaster. (DW: Delta and the Bannermen)

It is unclear if there were multiple toll ports.
