Hi Frankie,

You're absolutely right. The Phoenix Park & Hucknall services are distinct just 
sharing the running ways, but co-branded as NET-1. I think some Hucknall line 
services terminate at Bulwell in the evenings, but that's it in terms of 
complexity. I added a couple of stops to the relation on the one-way sections, 
but obviously used the wrong role (forward).

Originally I just created the relation to get it into OPNV-Karte, but obviously 
these things can (and should) be refined. I don't know how this will change 
once NET-2 & NET-3 come into the picture, but we have plenty of time to refine 
how to model these things.

Jerry

I've just been updating a few street-names along the route of the Nottingham 
Tram
>

Incidentally, the Nottingham Tram (sorry, 'Express Transit') relation - 
http://www.openstreetmap.org/browse/relation/170076 - highlights an interesting 
issue.

As it stands, the relation makes it look like there's one service - 'Line 1' - 
which stops at both Hucknall and Phoenix Park. This kind of makes some sense, 
in that they're both labelled 'Line 1', but in another sense there are two 
types of tram service, Station Street to Hucknall (and back) and Station Street 
to Phoenix Park (and back). From a routing perspective, we'd probably want to 
have a separate relation for each service (I'm guessing).

The one-way loop can probably be handled just using the forward/backward roles 
on the ways, so I don't think we'd need 4 relations (both destinations in both 
directions).

I've also been adding the station nodes as role=stop (not sure whether this is 
100% necessary, but it can't do any harm).
