That Hull crossing (I take it this is a railway LC, not a tramline) looks, from the aerial view at least, just about on the margin of what I would consider negotiable, but evidently Shaun's account and experience would make one have to think again! A lot probably depends on how well the rails are flushed into the roadway. I have crossed railway LCs at 90° which I regard as hazardous, yet other LCs at angles like that one, which I consider safe.
But the Norway example above looks a no-no to me! A shame, because I've always thought of the Scandinavian countries as very cycle-friendly, and I would assume that at dangerous junctions like this one, cyclists would be offered a dedicated cycle path (which I would use in such circumstances). But perhaps that junction is too far out from the city centre, and road is too narrow, to merit this?
A word about the Croydon network, which is relatively modern (built about 10-15 years ago). Most of it is off-road or on dedicated lanes: indeed a long stretch (Croydon to Wimbledon) makes use of a former mainline railway track. So the issue of cycle interaction doesn't often occur. Most of the places where the rails are flushed with the normal road surface and can endanger cyclists, are in the town centre: the junction I illustrated is one of the exceptions being several miles out of town.
