The electric locomotive 242 BE 1 of the Compagnie du chemin de fer Paris-Lyon-Méditerranée , later 2BB2 3301 of the SNCF , was a test locomotive for passenger train service. The locomotive was assigned to the Chambéry depot and was used on the north ramp of the Mont-Cenis railway in the Maurienne , which was electrified with 1500 V direct current , before it was scrapped around 1961.
commitment
The 242 BE 1 was intended for use on the Culoz - Modane section, which was electrified with the third rail . It was delivered in April 1925 and was first tested on the network of the Paris – Orléans railway, which was electrified with catenary , before it was transferred to the Chambéry depot in July of the same year. The test runs were continued on the first live section Chambéry - Saint-Pierre-d'Albigny of the future route, with the 242 BE 1 being the first locomotive that was available for tests. It proved its worth and served as the basis for the larger and more powerful PLM 262 AE .
From 1934 the locomotive was withdrawn from passenger train service and only used for freight trains between Culoz and Saint-Jean-de-Maurienne . In 1961 there was a rollover in a traction motor so that the locomotive was parked for a long time before it was scrapped.
technology
The car body rests on the two closely coupled bogies and does not absorb any tensile forces. Each chassis is equipped with a running bogie to improve the locomotive's running characteristics. The manufacturer MFO of the electrical part used the Oerlikon single-axle drive to transmit power from the four twin travel motors to the driving axles . The 242 BE 1 was the first locomotive in France to be equipped with its own ventilation system for the starting resistors.
