    I travelled on one of these from Rome to Venice, I'm sure I was happier on my journey knowing the train looked cool as it sped through Umbria and Tuscany.
    Science isn't about why, it's about why not. You ask: why is so much of our science dangerous? I say: why not marry safe science if you love it so much. In fact, why not invent a special safety door that won't hit you in the butt on the way out, because you are fired. - Cave Johnson

      As I have said in previous railway related posts (and I don't want to be accused of repeating myself) the critical factor in determining a maximum velocity on any non straight section of line is the strength of the wheel's flanges regardless of bogey configuration be it BO-BO or CO-CO.

        I don't really want to get into a conversation about trains but wasn't there a rail disaster in Germany where the wheels were to blame? They had a rubber cushion in them and it failed IIRC?

          Indeed and it was all down to the flanges.

            Nah, not really.

            The actual problem is solved in a slightly different way on the front of modern lorry tractor units, where one doesn't really ever want to couple to the unit in front.

            The thing to notice is the similar recessing of the slab window and skirting down ground level.

              I think its time to dig out a copy of Hoerners Fluid-Dynamic drag...

                There is a simple explanation for the cool appearance of this train, which does not involve complicated aerodynamics.

                It is Italian.
                And what exactly is wrong with an "ad hominem" argument? Dodgy Agent, 16-5-2014

                    I’m just arranging my trip to the Stockholm Tens
                    and while booking the train tickets I came across this picture of the Copenhagen to Stockholm train. What a strange looking contraption. Aside from the aesthetic eccentricities, I wonder how good the aerodynamics are at 160km/h.
                    Oops, just gave you negative rep for this interesting thread and observation that was intended to be positive. D'oh! No undo facility either

                      I recommend planning a trip from anywhere in the UK to Hanoi (yes the one in Vietnam), you can travel there all be train!

                      The gal upstairs from me had done this, travelled on the trans siberian express, just imagine not only does the landscape change before your eyes but so do the people, just imagine....
