The Tampere tram is a light rail commuter train system in the Finnish city of Tampere. It features I don't know km of track. It is currently running Santalahti-Hervanta services and Tays-Sorin Aukio services. The Linnainmaa-Pirkkala services are scheduled to commence in 2026 and the Lentävänniemi services should start next year. The route is one of the only lines in Finland that uses standard gauge. The Linnainmaa-Pirkkala services are branded as line 1. The Hervanta-Lentävänniemi services are branded as line 3.
So... this suggestion isn't bad, however it is a little out of place in TSW. But! It'd fit really well for a possible DLC for City Transit simulator
