Re: Sandy Biggest Atlantic Storm Ever
And I understand you have some problems with... what's it called... ram heating? piston heating? The trains have been running so long in the tunnels that the tunnels have actually been heated up by compression of air by the travel of the trains. I thought that was interesting as I never thought of that problem in such a cool climate. Tokyo is very hot in the summer and usually above freezing in the winter, but the tunnels dont seem to have this problem. Perhaps the clearance is greater. I think Japanese subways are running on British narrow gauge tracks, but Im not sure.
