ZAGRO Bahn- und Baumaschinen GmbH delivered two Unimog U 423 road rail vehicles to the municipal transport company STIB-MIVB in Brussels. In addition to the bus and tram lines, the company operates four metro lines. Every day, thousands of commuters and 1.1 million inhabitants of the Brussels-Capital Region are transported. Therefore, the public transport system cannot afford delays and failures. Flexibility, reliability and cost-effectiveness of the road rail vehicles played a decisive role in the decision to purchase a new one.
The vehicles are equipped with the ZAGRO turntable rail guide, which was developed for safe driving on the tight curve radii. Two Unimog road railer are suitable for winter service. For this purpose, the work vehicles received a platform with an integrated sand/salt spreader as well as a snow plough and a front sweeper, which can be mounted alternately at the Unimog front. In addition, the Unimog were equipped with an electronic brake system for controlling the tram brakes, a front weight with coupling options and a coupling bar for the towing of trams.
