Similar to the way Google Maps already provides information about how crowded a train may be at a certain time, the app will now also provide crowdsourced answers about the temperature of a given train, public transit lines with accessibility entrances and seating, and trains that have security on board.
Google is also adding some insights specific to certain regions around the world, such as the ability to see how many carriages are available on a specific train in Japan to increase your chances of getting a seat.
