      10.01 Essentials of the following Trains system

            (1) Where trains are worked on the Following Trains System,
            they may be dispatched from one station to the next, following
            each other in succession in the same direction on the same line
            in such manner and at such intervals of time as may be
            prescribed by special instructions.

            (2) Trains shall not be worked on the Following Trains System
            unless the Station Master of the block station in advance has
            exchanged messages regarding his readiness to receive the
            trains and has, in addition, given his assurance that no train
            will be allowed to leave his station for the station from which
            the following trains are to be dispatched, until the latter
            have all arrived at his station and until he has received
            permission to dispatch trains in the opposite direction.
