Reduction or fine?

The Dutch railways (NS) has plans to invalidate their reduction card between 17pm and 19pm, to avoid busy trains during these rush hours. The initial reaction to this announcement will probably be that it is unfair, since people holding a reduction card pay for this reduction so they should be allowed to use it. Well, fair enough, but apart from this problem, this new rule will carry some other implications.


Suppose a person wants to travel by a train which leaves at 16.30pm and is suppose to arrive at that person's destination at 16.55pm. This does not seem like a problem. However, what if the train is delayed and now arrives at 17.10pm? Technically, this person is travelling in non-reduction time, but he couldn't have known this before he got on the train. So, is he supposed to be fined or not?

Let's make the problem a little more complicated then. What if this person's train leaves at 16.30pm and is supposed to arrive at his destination at 17.10pm? In this case the traveler knows on beforehand that he will be travelling in non-reduction time. However, the largest part of his journey is in the reduction time. Does he have to buy a full-price ticket for the whole journey even though the largest part of it is in the reduction time, or not? Does he have to leave the train at the last stop before 17pm to buy a full-price ticket for the last 10 minutes of his journey?

The same problem exists for the other side of the time border. What if a person has to take a train that leaves at 18.45pm and arrives at his destination at 19.40pm?

Of course, the non-reduction time already exists in the morning. However, this time limit has only one border, since the reduction card now is not valid only before 9am. This still implies the same problem as the person leaving on the 18.45pm train, but does avoid the delayed train problem.

A remaining question is, of course, whether this non-reduction time rule will have a noticeable effect. People who take the train to go to work will still take the train at the same time, since that is the time their working day ends. People that have arrangements in the evenings, will also still take the same train to arrive on time for their arrangements.
Who remain are the people that travel by train to go out for a day. The morning time limit may work for these people, since they might make the decision to leave after 9am instead of earlier. However, these people will probably not travel between 17pm and 19pm anyway. They will probably try to avoid the rush hour anyway, or try to make the best of their day by extending it and not take an early train back.

So, try to weigh off the advantages of the non-reduction time against the disadvantages. Are the advantages worth the trouble?
