Bombardier Transportation in the context of Passenger car (rail)

The premetro and tram route 4 in Brussels, Belgium, is operated by STIB/MIVB, and connects the Stalle Parking stop in the southern municipality of Uccle to Brussels-North railway station in the municipality of Schaerbeek. It was created on 2 July 2007 as a new route between Esplanade and Stalle Parking. On 31 August 2009, the route was shortened with a new terminus at Brussels-North, while line 3 was expanded between Brussels-North and Esplanade. The colour of the signage for this line is pink.

Following the disbandment of line 3 in 2024, only tram lines 4 and 10 remain in the North–South Axis that runs underneath the Pentagon (Brussels' city centre). Both lines 4 and 10 have a 6-minute schedule during rush hour and are serviced by the modern low-floor trams (Bombardier T3000 and T4000).

A rubber-tyred tram (also known as tramway on tyres, French: tramway sur pneumatiques) is a development of the guided bus in which a vehicle is guided by a fixed rail in the road surface and draws current from overhead electric wires (either via pantograph or trolley poles).

Two incompatible systems using physical guide rails exist: the guided light transit (GLT) designed by Bombardier Transportation, and the translohr from Lohr Industrie (currently made by Alstom and FSI). There are no guide bars at the sides but there is a central guidance rail that differs in design between the systems. In the case of Translohr, this rail is grasped by a pair of metal guide wheels set at 45° to the road and at 90° to each other. In the GLT system, a single double-flanged wheel between the rubber tires follows the guidance rail. In both cases, the weight of the vehicle is borne by rubber tires to which the guide wheels are attached, which make contact with the road on concrete roll ways designed to minimise impact on the ground. Power is usually supplied by overhead lines, rechargeable batteries, or internal combustion engines where there are no overhead wires.
