A clear opening width of up to 1,400 mm and an excellent pressure seal up to 6,000 pascals offers passengers
high levels of comfort. The seal prevents unpleasant pressure fluctuations inside the train
caused by aerodynamic effects at high speeds.
E3D also has a highly sensitive obstacle detection system. If it is triggered while the door is closing, it
stops within a fraction of a second until it receives a further close command.
Intelligent sliding step
Another new development from Knorr-Bremse showcased at InnoTrans 2010, was an intelligent sliding
step developed for double-decker trains. This is equipped with an ultrasound sensor that measures
the distance from the platform and calculates how far it needs to extend, stopping the step automatically
between 3 and 4 centimeters from the platform edge. By reducing the gap and height
difference between step and platform it offers greater safety especially for elderly people. The system
is also equipped with a contact strip to prevent passengers becoming caught in the step.
Series assembly of door systems
Door manufacturer IFE has further expanded its door assembly services. In addition to first assembly, it
now also offers specific assembly aids and diagnostic instruments – or alternatively it can even carry out
full series assembly for the customer. In 2010, as part of the negotiations on equipping the FLEXITY 2
platform, IFE concluded an initial agreement on door system assembly with Bombardier.
Vehicle manufacturers are increasingly relying on specialized systems suppliers to take over the task of
door assembly. Using expert technicians from the original equipment manufacturer is the only way to
ensure correct installation. When IFE assembles the door systems itself the company is able to offer a
guarantee that includes pre-defined standards of reliability. Such high standards can usually only be
achieved through skilled assembly by an expert.
