In Japan, the average trains delay is 96 seconds. It is not magic, his secret is called “Paka-Yoke”

We are not going to discover anything if we tell you that the high Spanish speed has not lived its best summer. To get an idea, Four out of 10 Renfe trains They have suffered some type of delay. We have had breakdowns, Lost trains during the night and the final tip of the fires.

But beyond summer, the truth is that the Spanish road network is giving important symptoms of fatigue. Only last June, The birds arrived with a medium delay of 19 minutes About the scheduled time. In April the figure was almost 21 minutes.

According to the published report by the company, of the 9,607 trains that circulated last June, only one in three arrived in time Or they were delayed less than five minutes. We know this because Renfe herself has published it but the breakdowns have also affected the trains of Iryo and Ouigo that have to circulate on the same ways.

The data point to two possible reasons. First, Spain begins to give symptoms of having an infradimensive infrastructure to host the arrival of new operators (OUIGO and IRYO) and a Growth sustained in the number of trips. Second, the data warn that not enough has been invested in maintenance and modernization of the roads. It is very likely that the situation we are living is a mixture of both reasons.

But a question overwhelm: if in Spain we have problems with three trains companies … how do they work in Japan where six different companies operate?

96 seconds

Move by Japan, especially for Honshu (his main island in which cities like Tokyo, Kyoto or Osaka are found) is very simple if you decide on the high -speed train. The frequencies are so bulky and the delays so exceptional that the reliability in the system is absolute.

The known as Japan Rail It can, also, be chaos for those who visit the country for the first time, taking into account that even Six companies operate on their lines. However, each of them has its own reserved space so they do not compete on the same roads as it happens in Spain where Renfe has to deal with Iro and Ouigo.

Despite this, four of those Six companies (JR East, JR Central, JR West and JR Kyushu) are completely privatized and only two (JR Hokkaido and JR Shikoku) are state -owned. There is, however, a fundamental difference.

In Spain, following European orders, the management of the roads falls exclusively on Adif (which was public and also had to be privatized) that charges some canons to companies that want to operate in their railway framework. AND The roads are shared partly between medium distance and high speed trains.

In Japan, however, companies manage infrastructure and maintenance of the roads in which they operate but the network of Shinkansenthe famous bullet trains, have a completely separated infrastructure from the rest of the trains and is managed by the Railway Construction, Transportation and Technology Agency of Japan (JRTT).

This physical separation allows to reduce the risks (a fault of a slower train does not impact bullet trains) and install systems specifically designed for this type of trains. That has allowed them to evolve the acquaintance concept of Paka-Yoke which can be translated as “failure proof”, referring to the fact that all human decisions are supervised by an exahustive system monitoring system, which shields the network of those possible human errors.

This has allowed Japan to be a reference in world high speed. Until Spain and China surpassed the country in railway kilometers of this type of trains, the Japanese country was a leader but it still is in punctuality. In 2024, The average delay in the Tokaid line was 96 seconds. However, systems are designed for trains to enter a margin of 15 seconds at the station. Most of them stop in the first 6 seconds scheduled.

Japanese punctuality is an extremely valued quality. Culture forces to ask for public forgiveness when schedules are not fulfilled, sometimes reaching surreal extremes. Like the day that a railway company had to make its face because one of its trains He left the station 20 seconds earlier than expected.
