Had management spent a bit more then it could (and was going to) have been operated from Edgware Road signal cabin. However, maybe a blessing in disguise, the events of July 7th would have meant that had they carried out the installation in full, a service would not have been able to use the crossover - Edgware Road being out of action. The above quote from the thread about the Royal Oak crossover has made me wonder if it is possible to operate points on the spot if they are normally operated remotely. i.e. if these points were normally operated from Edgware Road would there have been a way of operating them by level or whatever at the site?

Yes. The air could be taken off the points and them moved manually, then the route secured using scotch and clip, before a train can be authorised past.

when we do point maintenace of a night we take the air of the interlocking machine so then the signalman can not pull of routes, then we remove the fuse supplying the feed for the valves, then we disconnect the air on site so we can move them manually.

However, it is extremely rare to use such methods on a passenger operating railway. Using a properly planned procedure, across what are normally manually operated points is quite different to taking air off of normally controlled points.
I doubt the service would have operated in quite the same way.
