The CMM 400-2 is a diesel multiple unit produced by Materfer in Córdoba Province, Argentina. The units are produced in Argentina's three primary track gauges and the standard gauge variants were the first to be produced for General Urquiza Railway services in Entre Ríos Province.

Overview

The DMUs come in 1000mm, 1435mm and 1676mm track gauges, and can thus be used on any part of the network with the exception of a few tourist services. Most components are built in Argentina, with the exception of a few such as its German Knorr Bremse brakes and Swedish Scania engines. The possibility of upgrading the Scania engines to more powerful Deutz AG engines on all future and existing rolling stock is being considered.

Some of the passenger comforts in the cars include; air conditioning, pneumatic suspension, reclining seats and LED lighting. Each car has a capacity for 70 seated passengers and each trainset has a conductor's cabin on each side.

Usage

The units can be found on a variety of different urban and inter-urban services in Argentina. The first trainsets were sent to Entre Ríos Province for inter-urban services on the General Urquiza Railway's Paraná - Concepción del Uruguay line.

The units on the General Roca Railway are used for inter-urban services between Bragado - Realicó - General Pico in Buenos Aires and La Pampa provinces. CMM 400-2 trainsets will also be used for the Tren del Valle when it opens in 2015, and some have already undergone testing on the line.

CMM 400-2 trainsets on the Mitre Line are used for its diesel branch between Victoria and Capilla del Señor. These units had serious problems when they were incorporated into this branch since the tracks had not been replaced beforehand and the poor condition of the tracks led to mechanical failures.

In 2015 the first narrow gauge units began to arrive in Chaco Province to begin operating on a General Belgrano Railway branch whose tracks were completely replaced in order to run freight and passenger services along the entire width of the province. Their bodywork has a slightly different appearance to the standard and broad gauge units found on other lines.
