  Quotations
  Some ten years ago, an evening excursion train from the Walsall area to Manchester, when travelling well over the heavily-graded Walsall-Rugeley line, was brought to a stand at a level crossing at Hednesford by the tardiness of a gatekeeper, who was pottering about in his garden instead of attending to his duties.
