[OSM-talk] User WJtW - railway track counts

[Dave F.]

I'm unsure of the difference between passenger_lines=* & tracks=*.

Reading the wiki page, it appears the writer is confused as well, 
stating in the last paragraph, that the 'passenger' bit is redundant as 
"all kinds of tracks connecting the same railway stations or junction 
should be counted with no regard to the train services running on it." & 
it's a "workaround" for tracks.

Cheers
Dave F.
