>>1527058JRs already have peak/normal/off-peak season fare for some trains?
And there are also early booking discount
On the other hand, according to my understanding, the fixed cost, especially vehicle deprecation cost for railroad is less than airlines, so that unlike airlines which need to use their aircraft to spread out the cost of their aircraft, train companies can simply park their trains when it's not necessary.
But anyway, this news isn't about changing fare on long distance trains, instead it's about the fare for daily commute inside city, so that like if you travel between 7-8 am you get to pay more, but if you're willing to travel at 6 or 9 am you get to pay less.
