On the plus side though the extra room means that your escalators can have several people using them at once. This means that you can have a group of people with push chairs or trolleys all use the elevators to go upstairs or downstairs at once. That means that you encourage the flow of ‘traffic’ upstairs and down for people who have trolleys, and the reality is that a trolley is not even really suitable for an elevator on its own. You would have to wait for a long period of time while your elevator came after you called it, and then you would have to cram yourself into the small space. The extra weight can also be unnerving for some people using an elevator. With an escalator however people can push the trolley on then wait, and lots of people can use it at once with no need to queue. This means more people going upstairs with trolleys and thus more custom.
