Low-Clearance Rapid Transit

LCRT is a hybrid concept between tram and metro, minimising construction effort while still earning the benefits of grade-free alignment

The aim of the concept „Low-clearance Rapid Transit“ (LCRT) is urban rail transit combining optimally the cost advantages of a tram and speed and reliability of a metro. Compared to existing rapid tram concepts, the following innovative factors contribute to this goal:

• The LCRT line is running mainly on street level (preferably divided from the surrounding area by fences or railings), instead of a track alignment continuously above or below street level, crossing roads are passed under via separated underpasses.
• Underpasses are realised only for major crossroads (at about 250 – 400 m distance between them), crossing minor streets are cut for motorized vehicles but equipped with protected level crossings for pedestrians.
• LCRT-vehicles are of significantly lower overall height than conventional tram or metro vehicles, so underpasses can be constructed much easier.
• Next to the underpasses, not only the LCRT track is lowered, but also the street surface is elevated, so the underpass ramps get shorter and the construction masses are reduced.

I'm a specialist for passenger transportation and timetabling, not for construction or rolling stock engineering. The initiative to make LCRT reality should come from a city, or better, from several cities together. Development of LCRT on the machinery and construction side will probably not happen on the initiative of the industry.
