Energy-saving escalators February 11th, 2009
Have you noticed? When no one uses the escalator in the metro for a while, it slows down. And as soon as someone steps onto it, his presence is detected, signalling for a gradual return to the escalator’s normal operating speed.
Several specially marked metro escalators are fitted with this energy-saving device, as it is designed to extend its service life, while lowering maintenance and electricity costs.
All escalators will eventually be energy-saving escalators. Another smart thought, another small action.
