To answer Michael's comment of some time ago, Brent Council may have removed the railings at the junction of Furness and Wrottesley Roads to actually enhance safety.
There are two ways this could be true. There is evidence now that when a cyclist gets brushed by a vehicle, such railings are more likely to lead to a fatality since the cyclist gets squashed between the vehicle and the railing. The lack of a railing would send the cyclist sprawling, but cause less damage. The other possibility is that it causes pedestrians to walk into the middle of the road as they tend to prefer the most direct route, which is certainly my own experience of that junction. This was the reason I campaigned for similar railings to be removed on Station Approach.
