On September 6, the model car of the western Colombia tram project developed by CRRC Changchun Railway Vehicles Co., Ltd. rolled off the assembly line in Changchun. The roll-off ceremony was held in Colombia and Changchun via video. According to the introduction, the trains of the project are six grouped low-floor trams. When running, two trains are reconnected, reaching the international leading level in terms of body length, bearing capacity, traction and braking performance, intelligence level, comfort level, etc., and they are tailored to the local urban rail line environment such as high altitude, big ramp and long station spacing.

The western tram project is a commuter channel connecting Bogota, the capital of Colombia, with cities in Cundinamarca Department. After the trains are put into operation, they will benefit millions of surrounding residents, greatly shorten people's commuting time, fully stimulate local employment and promote the economic development of cities along the line.
