Cycleway not rendered through tunnel

[DaveF63]

Hi
https://www.cyclosm.org/#map=15/51.3639/-2.3492

Is there a specific reason Cycleways are not rendered through tunnels?

No, this is a bug.
But I can't understand why it's not drawn where as here it's ok https://www.cyclosm.org/#map=19/48.86459/2.31979/cyclosm

Same issue here https://www.openstreetmap.org/way/124759292 https://www.cyclosm.org/#map=15/45.0035/3.8913/cyclosm
May because of I guess (we don't render underground railway)

railway=abandoned
tunnel=yes

[DaveF63]

So a test for the value of the railway tag needs to be included to ignore abandoned/disused/razed?

[Florimondable]

highway tag should prevail over railway one I'd say.

This is indeed a bug. We hide any railway with tunnel=yes (https://github.com/cyclosm/cyclosm-cartocss-style/blob/master/project.mml#L529). It should probably read

railway NOT IN ('light_rail', 'subway', 'narrow_gauge', 'rail', 'tram')

instead of the railway IS NULL test.

I'm not sure, I think we can have the real case of a tunnel with a road shared with a train (with rail on it), like :

highway=tertiary
railway=tram

few examples in île de France:

I think we should render as long as there is the highway tag.
