The present writer was once asked to name what he considered to be "the most typically English railway approach to a town": a somewhat tall order, especially as such matters will always be, in the last resort, of individual opinion. But the unhesitating answer to this question (which has not been altered after many years of extended travel throughout England) was "Sudbury, in Suffolk."

"Only as an absolute last resort will we carry out enforcement in the form of fines. We are sure that the public will want to be responsible and do their part to protect others by wearing face coverings."
