The wiki page Relation:route is an overview over all types of route
(hiking, cycling, ferries, trains, …). In addition, the public transport
part seems outdated. If you were able to read German, I would suggest
you to read DE:Public_Transport which describes the current status of
public transport mapping (its English counterpart is outdated, too).

"stop:n" is totally outdated and was necessary at times when relations
were not ordered list (AFAIK OSM API v0.5).

The proposal page
https://wiki.openstreetmap.org/wiki/Proposed_features/Public_Transport
is AFAIK the best English documentation.

Best regards
