Nice to know that LU apparantly sees no reason to feel worried itself.
I'm not convinced that the driver of the stationery northbound train
would be entirely indifferent to the unexpected approach of a train
proceeding towards him from the north. Filling his pants would perhaps
be a more likely scenario. Have there not also been "incredibly rare"
cases of trains "running away" in the "wrong" direction unchecked
because trainstop devices are set up on the premise that if trains are
going to do something naughty they'll always have the courtesy to do
it whilst proceeding forwards in the correct direction of travel?
