🚇 Subway

This is a subway, which is a fast, large-capacity, electric-driven rail transit built in cities, and is often found in densely populated areas. Among them, the lines located in the central city are basically located in underground tunnels, while the lines outside the central city are generally located on viaducts or on the ground.

Different platforms depict different subways, which are mainly white, blue and red. Messenger, LG and HTC depict subways located on the ground, while other platforms depict subways located in underground tunnels. In addition, except for the au by KDDI platform, which is represented by a big letter "M", other platforms depict an oncoming subway. This emoticon can represent subway, urban traffic, transportation, road transportation and daily travel.
