The Sydney number is a circular reference to Wikipedia, i.e. the NewsCorp article https://www.news.com.au/technology/innovation/network-map-shows-sydneys-massive-former-tram-system/news-story/011abaf90477768751377ce7b6689dcf is just citing the wikipedia page. (The map is taken from wikipedia). The date is also wrong, should be 1961. An independent reference would be good.

Warsaw

The data provided here for Warsaw seems to be off (132km). What was the source of it? Please compare it with Trams in Warsaw Pawelmod (talk) 07:11, 31 May 2023 (UTC)[reply]

Line length, track length or route length?

This list needs to be standardized on one of the above - route length, track length or line length - and that needs to be specified - explicitly - and adhered to. These terms are used interchangeably - and, in some cases incorrectly - in the list.

Chicago Surface Lines, for example, peaked in 1934-1935 at 1,673.9 km (1,040.1 mi) of track.

The route length was 847.1 km (526.3 mi). Line length - the length of all services, added up without regard to duplication - would have been significantly larger.

Contrary to what some people assume, the "length" of Soviet tramways was reported as track length. At 1989, the reported track length for St. Petersburg was 688.3 km (427.7 mi). The system was virtually all double track, so the route length was about 344 km (214 mi). 222.154.226.148 (talk) 10:27, 13 December 2023 (UTC)[reply]
