Old metro stations
Many major cities of the world are faced with transport problems of old subway systems. Some of these systems were built more than a hundred years ago and require immediate modernization to meet modern requirements and standards. In many metro station systems, only elevators are equipped with elevators. These are usually wide lifts, slowly moving between the levels of the station. Passengers are forced to wait for a long time, and the total throughput of the station is very limited because of this. The use of spiral escalators at such stations will increase their throughput and safety. They will not require additional costs, since it will be possible to leave existing elevators of elevators and not touch the architecture of the station.
