Subway stops are designated locations along a subway line where trains halt to allow passengers to board and disembark. Each stop typically has a platform, signage, and sometimes amenities like ticket machines or restrooms. Subway systems, such as those in New York City or London, have multiple stops that connect various neighborhoods and points of interest. The frequency of subway stops can vary based on the line and time of day. Some lines may have express services that skip certain stops to reduce travel time, while local services stop at every station. This system helps manage passenger flow and provides convenient access to urban areas.
