Assuming it does happen (either '14 or '20) the feeling is that it's
most likely to be an updated version of 96 stock.


Don't you mean an updated version of 95 stock (which I thought was an
updated version of 96 stock despite the name)?


Not necessarily as I believe the traction packages differ.


Yes, that's one element of the updating that was done to the 96 to
produce the 95. 96 stock has the whiney 1991-designed GTO thyristor
control, whereas 95 stock has more modern IGBT control.
