[quote user="schlimm"] [quote user="Sam1"]If a 112,000 lb. truck running 80 mph causes more wear and tear on a highway than a lighter truck running 55 mph, is it also true that a train running 220 mph would cause more wear and tear on rail infrastructure than one running 110 mph?    [/quote] Of course it does, both wear and power consumption (electric).  I have no idea about the French system.  The Chinese have dropped the top speed on the Beijing-Shanghai line for example, to 1319 km in 5:07 (average 159 mph), the top speed higher, of course, around 200 mph.   The German ICE3 trains still run at top speeds of 250-300 kmh (155 - 186 mph) and sustained (average) speeds of up to 135 mph on some routes.   But as you can see, those speeds are far above 110 mph.  A top speed of 110 -124 mph is attained by many non-HSR trains in Germany. [/quote] I appreciate your response.  Hopefully, an engineer with a strong rail technical background will be able to quantify some of the variables, i.e. a 10 per cent increase in speed requires X per cent increase in power inputs and causes Y increase in maintenance. I drive a Toyota Corolla.  Going from 65 to 70 mph is a 7.69 per cent increase in speed.  The incremental increase in fuel consumption is 9.6 per cent.  Presumably are similar curves for trains.
