The 2D2 5500 were electric locomotives operated by the Compagnie du chemin de fer de Paris à Orléans, then SNCF in France, in operation from 1933 to 1980.
Design and operation

This class originated on the PO with the two {{illm|2D2 5300{{!}}E 501–2|de|PO E 501 und 502}} class locomotives of 1925. These had four traction motors, one per axle, driving through Buchli drives and following Swiss practice. They were considered to be more reliable in service than other PO electric locos.
The locomotives operated from a {{1,500 V DC}} catenary with two pantographs, powering four {{convert|1,000|hp|kW|lk=on}} motors. Each locomotive had over {{convert|5,000|m}} of wire for the series-wound electric motors. The driver would start the engines in series, with only {{frac|1|4}} voltage applied at 350 A. The resistance applied to the engines was progressively removed and the locomotive's speed increased, then switching to series-parallel operation and finally parallel only at {{convert|100|kph}}. Rheostatic braking was also possible, with the rotors connected in series and shunt resistances across each field winding. Engineers watched the line ahead through a circular frosted lens in the windshield.

Thirty five units were ordered by the PO to run on its newly electrified Paris-Orleans-Toulouse/Bordeaux lines, numbers 503 to 537, delivered between 1933 and 1935. The next 15 locomotives were delivered until 1943 to the PO.{{cite web

The units travelled {{convert|220,000|km|abbr=on}} between overhauls. They were known to be very low vibration locomotives.
Service history
A 1946 SNCF film shows 2D2 5550 travelling on the {{convert|211|km|abbr=on}} Paris-Le Mans line, noting that 2D2 units delivered before 1942 had over {{convert|1000000|km|spell=in}} travelled, some over {{convert|3000000|km|spell=in}}.
Post-war, the Paris-Lyon line was electrified and an improved 2-Do-2 class, the {{illm|SNCF 2D2 9100{{!}}2D2 9100|fr|2D2 9100}} was ordered. 35 of these were delivered by 1950, but after this the rigid-framed electric locomotive was replaced by a Co-Co bogie design, the CC 7100.
