 After passenger services ceased on the Richborough Port branch, it was worked "on demand" to the facilities at Sandwich Road and Richborough Castle.The siding at Poison Cross amounted to Eastry's goods yard, so main line train engines ventured this far to handle vehicles if necessary (the short distance was a separate block section).Alarmingly, towards the end main line trains could be left waiting, even if they had passengers, for the engines to run as far as Richborough Castle and back if need be.
