Adverse Weather Conditions
How do you operate in windy situation including typhoon?
Just as railway services, when the wind speed become greater than 25m/s, the Yurikamome makes a stop at the nearest station to wait for the wind to lull.
What happens if there is an earthquake?
Anti-seismic measures have been considered since the design stage, for almost all part of Yurikamome Line runs on reclaimed lands.
The anti-seismic design was originally based on the data of the Great Kanto Earthquake (1923), but more measures such as the deeper piles and ground stabilization were considered to cope with possible liquefaction of the ground.
After the Great Hanshin Eeathquake (1995), we reinforced the route structures, including bridges, based on revised laws.
How do you operate in snow?
The trains operate as usual when the snow cover is 2 to 3cm high with the help of road heaters (Heating wire) and snowplows attached to the carriages. The trains may slow down (maximum speed 40 km/h) depending on the track conditions. The trains will run almost according to the timetable.
A snow melting agent is sprayed when the snow cover exceeds this height to prevent the snow piles from freezing. If there is heavy snowfall and the snow cover exceeds 10cm, the snow will be manually removed by engaging workers. The number of trains will be reduced (alternate trains).
What happens if the train stops in between stations?
If a train stops in between stations, the alarm is automatically issued in the central command office, and the position, train ID, type of disorder, etc. are displayed.
The command office decides on the measure and order all the personnel working near the location, including station staff and maintenance workers, to proceed to the troubled train. An emergency vehicle is used for a quick transfer of the staff. If it takes time to repair, a rescue train will be dispatched to stop parallel to the trouble train and take all the passengers to the nearest station.
