Journal Ashtead's Journal: Ghost Trains under Oslo
Even at the top of summer (the sun will be at its theoretical top point in a couple hours from now), there are talks about "ghost trains" showing up on the tracks in the Oslo Tunnel.
The phenomenon is that the track circuits that are supposed to detect trains present, get confused by electrical noise and fail as designed, that is, they indicate that there is a train present.
I guess the easiest way to fix this would be to add camera surveillance of the tunnel, so if some suspected ghost train were indicated, the controllers could have a closer look to see what was going on.
In related news, King Harald's model train set is on display.
The cucumbers are big and early this year....
