A time table
These are time table and complicated of a subway in Tokyo.
The surprising thing is that the time table in rush hour do exist although 23 trains run only in a hour of eight o'clock.
Most of these trains arrive on a station right on time.
This table is not a pose and this works very well because of the great effort of subway authorities.
But this punctuality sometimes work negatively.
107 people on a train have died of a train accident in April, 2005, around Osaka in Japan.
A train operator move the train at excessive speed to make up for only one or two minutes delay and the train went off the rails unfortunately.
Just only one or two minutes delay has taken 107 lives away...
