Hi there, I'm reverting this. The public_transport=platform node represents a bus stand not a bus stop or station. This station has 12 stands. The public_transport=platform node should be placed at the location people wait to board the bus. each platform can optionally have a corresponding public_transport=stop_position node that is placed where the bus stops on the highway. the name of both nodes should match. You can use Merthyr bus station as an example if you like, https://www.openstreetmap.org/edit#map=20/51.7443294/-3.3797592. Its is complete with bus routes. 

Kind regards,
Kits
