Users of the excellent Winter Tuesday 92 timetable might be interested in the attached snapshot. This is at 0543, and a track circuit failure at Etches Park has just been reported. Trains can still be made to leave the depot, and shunters can be forced back in by locking points and authorising SPADs. However, the line from Derby station to Spondon is blocked. The easy way round this is to send Spondon trains to Stenson Junction, where they reverse to access the freight line to Sheet Stores, but I wonder whether this would have been allowed in practice. The alternative is to sit tight and wait for the TCF to be fixed. In case anyone wishes to run the sim onwards I shall not spoil their fun by revealing how long this took.

Diverting via Stenson Jn is both planned for if the Spondon route is blocked for engineering work, and undertaken in case of unplanned events. The difference between the two is that for planned events care is taken to provide crews who sign the diversionary route, and route conductors where necessary for crews who do not sign, all of this being planned in advance. For an unplanned blockage of the route, trains can still be diverted subject to the crew signing the route, but in the event that a crew doesn't sign (both driver and guard must sign), it is often difficult if not impossible to provide a route conductor for just one member of crew on the spur of the moment let alone both. In this case the train would terminate at Derby, and in the case of a Sheffield - London service would either form a service back to Sheffield or maybe go empty to Etches Park, or wherever the set/crew was required next. Birmingham - Nottingham services (I'm thinking more modern TT's here) would often divert from Stenson to Sheet Stores and miss Derby altogether, again dependent on route knowledge, or terminate at Derby to form a Nottm - Birmingham/Cardiff service starting from Derby.
