Escalators - MAG could be speaking with Ottis and Kone as they have energy saving systems to stop Travelators/Escalators when not used/occupied after a variable time.
The problem of these systems are in the reactions of organic life forms.
Psychologically when we approach such static machines and that are fitted next to a wider normal walkway, evidence suggests people at a subconscious level assume they are broken and they continue down the normal walkway rather than walking on the the Travelator.
Interestedly if a single person makes the decision to walk onto the Travelator and it starts up individuals directly behind also follow suit.
Frankly you might a well simply switch the things OFF at times of low use -Just a fact.
Or even rip the things right out ,make an even wider walk way and perhaps add a few well placed seats !
