Strong wind measures

At Yokohama Municipal Subway, wind direction anemometers are installed at four locations along the railway line to measure wind strength at all times to measure wind strength. In order to ensure safe operation of trains.

19% (7.7 km) of all Yokohama Municipal Subway lines (40.4 km) are above ground sections and wind direction anemometers are installed at the following four locations.

• Sekine Bridge (Nakagawa-Azamino, on Route 246)
• Nippa Station
• Kami-Nagaya Station
• Sakaigawa Bridge (between Shonandai and Shimoiida, above Sakaigawa)

Wind direction anemometer

Yokohama Municipal Subway has two bridges.

• Sekine Bridge (Nakagawa-Azamino, on Route 246)
• Sakaigawa Bridge (between Shonandai and Shimoiida, above Sakaigawa)

Both bridges are less susceptible to the wind, as the floor is concrete and ballasts are laid on top of it, and walls are beside them.

Information from wind direction anemometer installed at four locations along the line will be sent to the general command station from "wind speed of 15m / s or more".
Based on this information, the General Command Station issues an alarm for each warning floor from the value converted to the average wind speed is "15 m / s or more", and operation regulations are implemented according to the warning floor.
