Working traffic lights for spawned traffic were an extension of traffic light controlled tram crossings and the various associated objects followed on naturally.
These objects provide graphic support for one way streets, multiple lane highways, traffic lights and tram intersections but the route builder has a lot of work to do to persuade traffic to flow in the right direction.
The tram tracks are designed to be sunk into the baseboard. Catenary is embedded into the track asset and follows the track centre line, making it suitable for trams with tracking trolley poles such as those by Silversmith <KUID:62391> and Motorman1066 <KUID:108959>. Matching support poles and accessories are available by both of these authors and there are various invisible stations available within the Station Kit packs.
