The Cobweb Bridge is closed due to an arson attack in August, I don't think there's any info on a reopening date. I don't know how to mark it as closed on the map, it would be good if route planners can know to avoid it.

Unable to answer "How many steps are here?" – Steps – osm.org/way/1002416573 via StreetComplete 58.0:

Not really steps, just a grass track with a couple of unhewn rocks forming steps

Steps continue down beyond what's marked on the map. 193 steps total from the top to the gate onto Happy Valley gardens, then about 11 to the main path below

Unable to answer "What’s the surface here?" – Foot Path – osm.org/way/409875874 via StreetComplete 58.0:

This is an access point onto the track, unpaved (grass/gravel) except for rubber matting around the rails. There doesn't seem to be any access to a path on the other side, where there is a fence. This is not the path slightly further north (visible in the second photo), which is mapped correctly

Unable to answer "Is there an air compressor available here?" – Birmingham Garage (Gas Station) – osm.org/node/455887749 via StreetComplete 58.0:

The garage looks like it's closed down long ago, but I can see things in the floor that could have been the site of petrol pumps. There's a sign in the window saying that the bike hire has closed down. No better photo as I didn't want to get in the way of the person with the car

Unable to answer "What’s this pole made of?" – Power Pole – osm.org/node/8230400346 via StreetComplete 57.1:

This is a wooden telephone pole, almost under the power cables so I think it's been added to the cable incorrectly.
