Electric locomotive RENFE 7122. IBERTREN 42030B

Electric locomotive series 7100 of RENFE, number 7122. Livery in unified green with yellow stripe, with snowplough. Era IV. Interface NEM for a 21-pins decoder. During late 1920’s the” Compañia de los Caminos de Hierro del Norte de España” (NORTE), in order to increase the traction power, started the electrification of its lines; from Barcelona to Manresa, from Barcelona to Sant Joan de les Abadesses and from Alsasua to Irún. The 7100 series based on the Oerlikon’s Swiss technology ran for those new electrified lines (1500V DC). In the middle 60’s the lines changed their voltage from 1500 DC to 3000 DC. This conversion involved to move the locomotives to others lines with 1500DC voltage. Therefore, the 7100 series started their service in the Miranda de Ebro Depot. This will be their last active duty (middle 70’s). The new service started with the RENFE unified green with yellow stripe livery, suffering some modifications, as the squared buffers and because of the heavy weather in the area was added a special support for a snowplough.
