That'd be all the Adtranz kit - when it's working - Electrostars, Turbostars
and the likes. I always thought that the Danish approach on the IC3s of
showing a pictogram of someone waving their hand in front of the door was
better, as that's far more likely to activate the (rather pathetic) sensor
than reaching for the "button" with one finger.
