Just had another thought. If a VIP is travelling on a train, are additional seats booked around them to be kept free for security purposes? Or could one end up sitting next the the King or PM if the train was full?
Usually a special arrangement is made to charter a dedicated carriage which would be a business negotiation outwith the NRCoT. Though having said that it did used to be documented somewhere that one could purchase a whole compartment or carriage to oneself by purchasing a ticket for each seat therein.
