    Eurostars were significantly limited in power on the 3rd rail, as the supply could only offer something like a third of the power available on 25 kV. The only
    reason the UK southern 3rd rail system extends as far as it does is for historical reasons. Now that multi-system vehicles are easy to build and design, there
    is really no reason to perpetuate such a system other than the expense of changing it out for something newer (see, also, the 25 Hz PRR NEC system).

    Oh, I agree, but getting up to 100 mph on the way to Bournemouth is
    still pretty cool.

    All the new electrifcation in London is OHLE and there are through
    services like Thameslink that are OHLE on one section and 3rd rail on
    the other.

    They said the M-1 fleet of the LIRR was able to 100 mph when
    it was new. I don't think it ever did in service.

    The SEPTA Silverliner IV's (1974) were supposed to do 100 mph
    but I don't think ever did in service.

    The NJDOT Arrow cars could do 100 mph and routinely did so on
    the NEC. At least until they were sent out for a rebuild, and
    then could only do 90 or only 80. Ridiculous. They added
    a half hour on the run between Trenton and NYC.
