(Continuation from yesterday)

To tell you the truth, I didn't get angry with this accident, because of the good time management of Yokohama Municipal Subway.

In fact, I know well that the recovery from a derailment accident is terrible difficult.

First of all, they cannot install a crane in a tube of subway, and can use only hydraulic jacks.

They should not use electricity to carry the devices to the accident place. The power should be shutdowned around the place for safety activities.

In addition, I appreciated their tasks that they estimated and opened the date and time of recovery, and they could complete it"

Compared with this case, even though declaring "we recover from the derailment accident within today", re-declaring "we cannot recover it within today" at dead of night,

Due to these stupid announcements, I had to work through the night at my office. So I would emphasize that the railway company should model after this case.
