I went to Fukuoka last month to do a little business. I really like taking the train from Kumamoto to Hakata station, but that method is not nearly as convenient as taking the bus (and it’s cheaper, too!)
Anyway, I’ll have to write about all that another time. I hadn’t been to Fukuoka on foot in a while, so I hadn’t been on the subways for at least a couple of years. To my surprise, the two stations I used had guardrails set up the entire length of the platform. I cannot recall if Fukuoka has had any troubles with people falling or being pushed into oncoming trains, but it has happened in other parts of the country. This seems to be a great pro-active move on the part of the transit folks. Nice job!
Just to show the contrast between lines with and without the guardrails, the above shot is from one of the stations on the Tokyo Metro line.
