A view of Edinburgh Tram 252 at the Edinburgh Airport terminus.
Note the very small gap between the tram and the platform.
The very small gap between the tram and the platform is shown in this view.
It should be possible to narrow the gap at Heworth and to straighten the northbound platform at Tynemouth for example.
Free onboard WiFi is shown by this window detail. So it should be possible to have it on Tyne and Wear Metro.
