Day in, day out, several hundreds of millions of people all over the world use public transport systems. Within a metropolis, this is usually the only cheap and efficient way to get from one place to another. Considering the rapidly escalating individual motor car traffic and congestions in big cities, public transport systems appear as an increasingly attractive alternative, and this trend poses a major challenge with regard to the existing infrastructures.
This evolution makes new demands on the rail-bound mass transit:
Growing metropolises require increased transport capacities
To enhance the efficiency of these systems, the boarding and alighting times are optimized, which results in more stringent requirements to be fulfilled by the door systems.
Highly available and reliable train doors are thus indispensable in order to guarantee an efficient operation of the railway systems.
