Talk:List of largest currently operating tram and light rail transit systems

Lack of clarity regarding applicable metric
This article does not seem to specify whether it uses track length, route length or any other metric to rank systems.

In fact, it seemingly conflates track length and route length (e.g. Melbourne: track length; Vienna: route length).

Melbourne does not seem to be the longest system by any of these two metrics. Plo290 (talk) 03:45, 12 May 2023 (UTC)
