    I used to work on those. It was quite the lightshow at night. Hard, dirty, and demanding job.

      Coalsmoke,

      Do these things ever set fire to the trackside vegetation? - there's a hell of a lot of sparks flying there.

        Sometimes they do. They have several tank cars of water in the consist for that.

          I only saw that grinder up here once working at night, and it is quite a site to see.

          Anyone know anything about the grinding wheels, or how long they last etc.

            Used to go by these things all the time. Mostly at night because the rails were always too busy
            during the day to give up the track. Couldn't help notice that everyone that worked them
            (that I could see) was totally covered in black crud. Realllllly dirty job. But definitely spectacular
            at night.
            John Titor, when are you.

              Another couple of impressive rail operation sights.
              Rail butt welder.
              In floor CNC truing lathe for locomotives wheels, the Loco drives over the lathe which then comes up out of the floor, turns the wheel set as it re-profiles it after taking a dia and low point measurement.

                In Germany, everything goes fast: http://en.wikipedia.org/wiki/High_Speed_Grinding

                Had never ever heard or seen this railway grinding thing, let alone milling it or profiling the locomoive wheels while mounted, but have seen some other night time ops done on the railways in Finland. Probably should ask my grandad, he worked his whole life on the train yards.
                Amount of experience is in direct proportion to the value of broken equipment.

                  Very important to maintain track and wheel profile to reduce wear and correct riding on the rail.

                  The wheels themselves are bored to match the axle and are press fit on to conform to a certain press-on tonnage/pressure.
