How odd, just not what I was expecting. Looks more like a combined Office of Departure (outbound) and Transit (inbound) than it does a clearance site. Seemingly only 349 spaces and with an in-line payment facility that I think is asking for trouble; so, yes, maybe more gridlock than Mrs Elphicke's logistics hub (or whatever). Does 'T' mean somewhere to powder your nose, do you think?
Just compared the above with Guston PC's site drawing; now I'm really confused, because it seems to have grown rather!
