Shmail's GLR Avenue station is also transit enabled as a bus stop. Unfortunately people seem to like buses alot more than Trams so you never seem to get any trams but you do get lots of buses. To make it work as a pure tram stop you first need to disable the buses. You can do this using the TE Editor component of SC4Tool.
The SC4Tool (SFBT) can be found at

The download link is hidden right at the bottom of the webpage. The TE Editor component is very useful and will enable you to remove the Pedestrian to Bus transits. It will then work as a pure tram stop. Looks good and works.
