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. 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 are multiple toll ports.
