Waiting to proceed through Bramble Lane station & Three Spires tunnel single line section. If the line is blocked, the signal is set to calling on which allows the 47 to draw its train forward to the shunt limit, before reversing back into the refuge siding. That is where good track laying pays off. That freight had fifteen assorted wagons, short, long & bogie wheels, but as always reversed without hitch. It makes for an interesting session of playing trains.
