'Miyako'
I sometimes think that the trains I enjoy most in Japan are those third or fourth 'rankers' that nevertheless offer some immaculate operation. Like this one for example.
This is the 'Miyako' ('Capital') half hourly service form Kyoto down to Nara, two former capitals of ancient Japan. It is a 'kaisoku' (limited stop) service taking about 50 minutes for the thirty mile trip. No great speed - but with most of the route single line and an 'all-stations' service to 'dodge around' in various loops together with six intermediate stops to make and several 'meets' with trains coming the other way - you'll appreciate that it needs to the second timing to make the service work.
These JR West Japan units offer a lovely view to 'gricers' too - you can follow every inch of the way as if you were sitting in the pssenger seat of a car.
