If you own 4 railroads and the adance to nearest railroad card is pulled how much do you pay, 200 or 400?

I presume that when you say "11 Routemasters", you mean the new "Routemasters" (Boris Buses) on route 11, as opposed to 11 examples of the original "Routemasters left in service?

If so, the rear platform entrance is open whilst the buses are running through the central London (City and West End) areas.
