Going back to Follonsby (Follingsby?) depot reminds me of my first signal box appointment at Wardley which controlled access to the depot via a ground frame release. Even in 1979, there were only a few booked trains a day -either 2 or 3 usually around 2200hrs. Other than those and ocassional East Coast diversion, there was only the Monkton coke exchange sidings to keep one awake!
