On each of the 4 central axles was mounted a hexapolar traction motor with a one-hour power output at the shaft of 722 kW for 560 amps at 1500 Volts. The lateral play of the driving axles was 25 mm (1 inch). Maximum speed was between 130 to 140 km/h.
The description of the pic is wrong. It does not show a "Nez de Cochon", it shows one of the two pre-series locomotives, which were called "Grand-mère" for grandmother. I guess that this name refers to the very first 2D2 electrics built with Buchli drives, which was followed by about 100 more engines. The evidence for the "Grand-mère" can be seen on the window arrangement in the side wall. "Grand-mère" has 6, the "Nez de Cochon" 8 windows in the sidewall. Furthermore, you see the shoes for the 3rd rail still fitted on these locomotives. These were left away for the series engines. For further information google for 'PO E501 E502'. 'PO' stands for the Paris-Orleans railway who ordered these locomotives, the rest is the road numbers. The second para with the tech description is ok, since they had almost the same tech spec than the series locomotives.
