I'm afraid the "silver bullets" don't run from Cornwall any more :(

They currently run from Antwerp in Belgium through the Channel Tunnel once a week; I believe the china clay is imported there from somewhere like Brazil (stand to be corrected on exact location!). When the flow started, the wagons were nice and clean, but that didn't last long.

Thanks all for the info on the now tarnished silver bullets. Thats another sign of the times where it isnt cost effective to keep anything clean and tidy. Maybe the tanks would have a better carbon footprint if were kept as clean as airfraft fuselages to reduce drag coefficient stuff?
