[quote]QUOTE: <i>Originally posted by futuremodal</i> <br /><br />Chernobyl, <br /> <br />Regarding axle loadings, remember that the railroad could do what the truckers already know - spread the load weight over more axles (go with tri-axle bogies or even an extra "centered" bogie) to reduce per axle weight for the same relative car gross. The current 286k on two twin axle bogies gives a max axle weight of 71,500 lbs per axle. Using two tri-axle bogies on a 315k (to allow for higher tare due to more axles) gives a max axle weight of 52,500 lbs per axle. It all depends on how low one would have to go determine the proper max axle loadings for a 200 mph ride. <br />[/quote] <br /> <br />Well - the rule is simple - the less your train weighs - the better. TGVs are 17 tonnes per axle (about 37800 lb). <br /> <br />Also - 200mph operation would need full aerodynamic shrouding of the train. <br /> <br />oltmannd: been there, done that, got the t-shirt ;) TEL proved not to work before - and nothing changed about it as of yet. <br /> <br />Jet-train locomotive was 4000 hp at rail at ~90 tons. TGV power car is 6000 hp (probably 7k+ short term) at 68 tonnes...
