Transit Systems | Public Transit Information Database

Comprehensive information about public transit systems worldwide.

Very nice! I think we're confusing route length and track length, though.
Can you elaborate further on this so I might be able to fix it? As best I am able to discern, system track length for all current ones is accurate.
Could track length include sidings and double-tracks and extensions and other maintenance track needs that aren't useful for the passengers themselves?
