SNCF 2D2 5500
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 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 catenary with two pantographs, powering four motors. Each locomotive had over of wire for the series-wound electric motors. The driver would start the engines in series, with only 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 . Rheostatic braking was also possible, with the rotors connected in series and shunt resistances across each field windin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rheostatic Braking
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an el ...

CEM Locomotives
Cem Sultan (also spelled Djem or Jem) or Sultan Cem or Şehzade Cem (December 22, 1459 – February 25, 1495, ; ota, جم سلطان, Cem sulṭān; tr, Cem Sultan; french: Zizim), was a claimant to the Ottoman throne in the 15th century. Cem was the third son of Sultan Mehmed II and younger half-brother of Sultan Bayezid II, and thus a half-uncle of Sultan Selim I of Ottoman Empire. After being defeated by Bayezid, Cem went in exile in Egypt and Europe, under the protection of the Mamluks, the Knights Hospitaller of St. John on the island of Rhodes, and ultimately the Pope. Early life Cem was born on December 22, 1459, in Edirne. His mother was Çiçek Hatun. In accordance with the custom for an Şehzade (prince) Cem was appointed to a provincial governorship of Kastamonu in 1469. In December 1474, Cem replaced his deceased brother Mustafa as governor of Karaman in Konya. Succession dispute At the death of Mehmed the Conqueror, on May 3, 1481, Bayezid was the governor o ...

Fives-Lille Locomotives
Fives-Lille was a French engineering company located at Fives, a suburb of Lille. It is now part of the Fives Group. History The company began as in 1861 and made a joint venture with the Société J. F. Cail & Cie. and were of Belgian origin. This co-operation led to expansion and the creation of several factories. One plant, located in the district of Fives, near Lille, specialized in the construction of rails and steam locomotives. Another plant in Givors on the Rhône specialized in wheelsets for railway rolling stock The term rolling stock in the rail transport industry refers to railway vehicles, including both powered and unpowered vehicles: for example, locomotives, freight and passenger cars (or coaches), and non-revenue cars. Passenger vehicles can .... The business developed and became, in 1865, the ''Compagnie de Fives - Lille'', then in 1868, the limited company ''Compagnie de Fives-Lille pour constructions mécaniques et entreprises''.
