European Railroad Discussion > TGV heatDate: 06/28/19 10:33 TGV heat Author: milkcow I would appreciate a short primer in how well European trains and tracks deal with extreme heat.
We have July 14 to August 12 planned (and bought) London-Paris-Munich-Krakow-Amsterdam London rail and Riverboat travel.,,,,,, My backup plan so far is a month at Inverness. David Date: 06/28/19 12:05 Re: TGV heat Author: exhaustED Steel melts at around 1400 degrees C.
Date: 06/28/19 12:22 Re: TGV heat Author: milkcow Apparently the steel in CSX tracks stretches and kinks at 83 degrees. I wonder if High Speed rail tracks in Europe are apt to do the same at 45.1 C.
60% of the autos have been banned from Paris, maybe we will have more friends on the trains David Date: 06/28/19 13:10 Re: TGV heat Author: PHall I was in Europe for the 2003 heat wave. They were not prepared or equipped for the heat.
Date: 06/29/19 01:41 Re: TGV heat Author: Hartington Here in the UK when heat gets "extreme" (whatever that means) the trains continue to run but at reduced speed (=delays). If heatwaves like the one in Europe at the moment continue I guess the railways will have to buy rail stressed for a wider temperature range.

David Date: 06/29/19 13:50 Re: TGV heat Author: nm2320 At this time TGV arrivals 10 minutes late at Paris, Gare de Lyon. At this time it is 22:49 in Paris and temperature is 91 degrees F. Reason given for late arrival is police action.

And of course heat tries to expand the rails, putting them into compression and risking sunkinks. A little caution is well advised. Date: 07/27/19 21:59 Re: TGV heat Author: exhaustED Delays caused this past week in the UK due to unusual temps... approx. >35degC.
