Concarril

Constructora Nacional de Carros de Ferrocarril SA (English: National Railway Car Manufacturing Company), more commonly known as Concarril, was established in 1952 (some sources say 1954), as a rail vehicle manufacturer owned by the Mexican government. It manufactured a wide variety of passenger and freight cars, as well as locomotives.

The Ferrocarriles Nacionales de México (FNM, or NdeM), the country's government-owned railroad company until the 1990s, purchased large numbers of railroad cars from Concarril, including various freight and passenger cars. The latter included sleeping cars in addition to conventional coaches. Dining cars were not one of its regular products; it built its first such car in 1989, for FNM. The company also built locomotives for FNM and other railroads, and undertook rebuilding (or refurbishment) work on older locomotives and coaches.

Passenger railway cars built by Concarril for urban rail transit use included subway/metro cars for the Mexico City Metro and light rail vehicles (LRVs) for the Guadalajara light rail system, the Monterrey Metro and the Xochimilco Light Rail line of Mexico City's STE. The company made both steel-wheeled and rubber-tired subway cars for Mexico City. It also supplied subway cars to the Santiago Metro, in Chile (specifically the NS-88 trainset as a replacement for an NS-74 train that was destroyed during a terrorist attack in 1986); that was part of an effort by the Mexican government in 1990 to boost exports of manufactured goods, which also encompassed a planned sale of 200 Concarril-built freight cars to Venezuela.

At the time of its sale in 1992 to Bombardier Transportation, Concarril was the largest manufacturer of railway rolling stock in Mexico.

The plant built a series of Electro-Motive Diesel locomotives. During its periods of ownership first by the government (as Concarril) and subsequently by Bombardier, the plant has built over 100 light rail vehicles for rapid transit systems in Mexico's three largest cities, Guadalajara, Monterrey, and Mexico City. The plant has built 70 percent of the rail vehicles in Mexico.
