Good grief! The bay exit even has a sand drag to protect it and they
manage this error!
The sand drag is to stop a train attempting to leave the bay siding onto the
eastbound track though, it doesn't protect the crossover points, which are
the third and fourth of four sets of points over which the train would
travel from the bay to the westbound line.
