This, it turned out, was easier said than done, though it was almost certainly one of the modern sliding-door affairs with room for a wheelchair or for one of those double buggies that provide such interesting and varied gymnastic challenges for other users of Britain's high streets and public transport.
The size of the new cubicles has led to their number being drastically reduced to the point where there may be only three toilets to cater for the needs of an entire train full of passengers. Instead of a quick trip to the facility at the end of the coach, travellers now need to embark on a lengthy and often futile quest to find an unoccupied cubicle.
Incidentally, it is, in theory, possible that the lavatory in this story was decorated with the winning image from c2c's design-a-door competition; with commendably creative sadism, the judges chose a large and vivid depiction of a dripping tap sure to be greatly appreciated by pent-up travellers waiting cross-legged in the corridor outside.
Anyway, this research ultimately led to a somewhat startling headline in the South Wales Evening Post:
