Unfortunately I don't have my books available at the moment (packed; expecting to move house) but I think Armargh disaster occurred under time interval working. One of the many incidents that fuelled the call for "Lock, block and brake". Looking at Wikipedia I think the only tickets involved would have been those of the passengers.
