Rule 55

British Railways Rule 55 is a rule which persisted in the 19th and 20th century. It says that if a locomotive stops on a mainline, it MUST let the signalman be aware of the presence of the train, to prevent serious accidents. This rule is known to be broken in the Thomas & Friends episode "Henry's Forest", which was criticized by Awdry himself for not following the rule.
Rev. W. Awdry: "Henry's driver didn't obey Rule 55, which means that the driver should've warned the signaller! That's unrealistic!"
