Two trains of KERS 7200 can have their rolling stock made up of five cars, but these trains haven't been used as 'K-Limited Express Orihime'; moreover, the KERS 7200 is equipped with the rollsign 'K-Limited Express,' so it can show the rollsign on its front car.
また、7200系も2本が5連組成可能であるが「おりひめ」に充当されたことはない（7200系は「K特急」の表示も可能）。
