Japan's railway services offer the most punctual and saftest service in the world. 1 behind the scene story around how safety is implemented.

If you ever plan to visit Japan, you will be pleasantly surprised by its railway service.

Japan's railways are said to be the most punctual and safest in the world--especially in the Tokyo metropolitan area.

One of the safety measures is called the Platform doors. Before it got installed, commuters may fall off the platform, which may cause hazardous injuries and train delays. Now fully implemented, the risk of falling accidents have significantly decreased.

Making these safety measures would not be possible without openness to adopt new technology and new ways of thinking.

Old way: Required extensive modifications to Platform doors and the train car. Expensive, but a long-time proven method.
New way: Embed QR two-dimensional barcode to the train car window, and set a camera at the station. Inexpensive, but rather new.

By adopting the new method, the implementation of Platform doors has significantly accelerated, but the best part is it's inexpensive:

Old way: $20M vs. New way: $27K (0.14% of the original cost!)

While Safety is super important, it doesn't have to cost an arm and a leg.
