y2k

This hasn't had a nibble in m.t.r.m, so I am trying it more widely,
starting with my own territory.

My students are working on an international challenge which seems to be
written by a Hollywood filmmaker:
Describe a railway crash in Japan caused by a y2k problem.

AFAIK, virtually all railway safeworking is protected by hardware, which
fails safe.  Computers are used for *control*, not safety protection.  The
worst problem which y2k could cause is gridlock: everything halts.
