50Hz-AC prototype EMU (Z-9055) of SNCF.
<p>
Actually a former Class 1300 "Standard" commuter EMU ex-Etat (Z-1320, 750V, live rail), rebuilt to 20kV-50Hz (OHLE), for the experimental 50Hz-AC electrification of Aix les Bains-Annecy.
<p>
Later upgraded to 25kV, renumbered Z-6004, and withdrawn in 1972.
<p>
This unit is seen somewhere between Aix and Annecy.
