(Continuation of yesterday)

This strategy had a point that two operations work simultaneously.

That meant that both my daughter and wife went to the examination place by trains, and I run with the trains by my private car at the same time.

The aim of this strategy was

"Wherever and whenever the trains stop, I can pick them up at the nearest station within 10 minutes by my car."

But it was difficult in fact.

Needless to say that, the speed of trains is faster than that of cars, and there are not necessarily roads near the lines of train. If I approach the trains too much, I cannot arrive at the target station on time. If I get away from trains, I am going to lose the purpose of this strategy.

However, I thought that there is a significance to try this strategy.

Without mentioning about physical effect, I thought that the mental effect will be expected.

If a train accident occurs, both a student and the guardian are going to be panic.

It must be difficult for them to think of a new route into a state of panic. Especially they become nerve if they could catch a taxi.

This strategy will give them a great relief, because a rescue vehicle always runs close to them.

I regarded these two operations as two systems.

This is called "Dual system". The whole system reliability becomes high by the two same system that work simultaneously

After returning home, both my wife and I reviewed the experiment results and train time table again, and modified subtle change of the operation.

In addition, I excised the installation of the car chain. Finally, the day of the examination was coming at last.
