[Tagging] Abusing name tags on type=route

[Michael Tsang]

Dear all,

According to the talk page 
(http://wiki.openstreetmap.org/wiki/Talk:Proposed_features/Public_Transport#name_as_.22prose_description.22.3F), 
the use of name=* key on a public transport route is considered an abuse 
(unless the route has a real name). However, without abusing the name tag, the 
life is difficult for both the mapper and the user. Consider the following metro 
route_master:
http://openstreetmap.org/relation/272132
There are, in total, 27 different variants of the line in the real world (2 
directions times 2 sets times 2 different branches with multiple short runs all 
under the name East Rail Line), mapped with different combinations of from=*, 
to=* and via=* keys. Without abusing the name tag users have difficulty 
selecting the correct service, for example in JOSM and OsmAnd.

How should we cope with the situation like this?

Michael
