What separates an S set from an R set?

編成記号（へんせいきごう）

This feature separates the N700 from the rounded 800 when both are plausible. JR West’s closely related eight-car S sets are the 7000 subseries. A distant nose view cannot distinguish S from R reliably. Look for the set marking or vehicle number; without it, record only “eight-car N700”.

Look for a broad shoulder sweeping out from the base of the cab beside the flattened nose. The plate represents JR Kyushu’s eight-car R set.

Can I distinguish an N700 R set from an S set by its nose alone?

The flattened nose and broad shoulders help distinguish an N700 from an 800. JR Kyushu’s R sets and JR West’s S sets look similar from this angle. Look for the set marking or car number. If you can verify only the formation, record “eight-car N700”.

Powered noses need shielding

Powering both end cars adds a noise-control problem near ATC equipment. The design uses lower motor shields and protected wiring to limit direct interference.

Seating

On the eight-car San’yō–Kyūshū N700, a typical ordinary reserved row has four seats. The non-reserved cabin in cars 1–3 has five across, so only the three-seat side has a middle seat. On Kodama, non-reserved cars 7 and 8 have two seats on either side of the aisle. Confirm the reservation designation for your departure.
