[OSM-talk] Layer transitions

[Harald Kleiner]

Hi!

to make my question more precise, please have a look at this tunnel that 
crosses a railway track (the railway is a subway that runs at ground level):

http://www.openstreetmap.org/edit?lat=48.1325961&lon=16.3109488&zoom=19&way=29205957

The tunnel tag implies layer=-1 and that leads to a junction of ways on 
different layers on both ends of the tunnel.
On the western end of the tunnel the adjacent way ends, this should be 
no problem with the layers; on the eastern end there is a T junction.

Do you think, this tunnel is OK the way it is or should someone add a 
small piece of way on layer 0 at the eastern end next to the T-junction 
to avoid a T-junction of different layers?

Thank you,

Harald
