One thing that has always impressed me about the Shinkansen is its near obscene punctuality:
Quote from http://www.wikiwand.com/en/Shi... :
The Shinkansen is very reliable thanks to several factors, including its near-total separation from slower traffic. In 2012, JR Central reported that the Shinkansen's average delay from schedule per train was 36 seconds. This includes delays due to uncontrollable causes, such as natural disasters. The record, in 1997, was 18 seconds.
