series E721 model representing the JR East South Tohoku area AC electrified lines, created for modern railway model enthusiasts.
- Background: The series E721 entered service in 2007 to renew rolling stock at JR East Sendai Depot and to serve the Sendai Airport Access Line. Designed for low-platform local lines, it features a low-floor body with smaller-diameter wheels and step-free entrances for barrier-free boarding. In addition to the earlier series 0 and 500 2-car sets, a fixed 4-car series 1000 appeared in 2016, and many variations exist including third-sector cars sharing the same basic design.
- Key features and option parts:
- The 6-car set models the P-7 formation (series 0) and P4-11 formation (series 1000) from the Sendai Train Depot. Underfloor equipment such as bogies and obstacle deflectors are reproduced in gray for the series 0 and bluish gray for the series 1000.
- Distinct livery stripe colors reproduced accurately by series (series 0: green, white, red; series 1000: green, white, pink). Car numbers, depot markings, and car position indicators are pre-printed.
- Window sizes on the toilet-opposite side are reproduced to reflect differences by series.
- Head and tail lights illuminate, with an on/off switch. Each lead car lights four headlamp units.
- New round-pipe PS109 type pantographs are newly manufactured for the model.
- Bogies: low-floor DT72 / TR256 types modeled. Small-diameter wheels with a 5.2 mm wheel diameter are applied to match the prototype; real-life axle spacing of 2,100 mm is faithfully reproduced. Snow plows are pre-installed.
- Coupler details on the 6-car set: KUHA E720-7 and MOHA E721-1011 are fitted with dummy couplers that include coupler covers; MOHA E721-7 and KUHA E720-1011 are equipped with coupling obstacle deflectors and coupler covers.
- Lead car couplers are compatible for coupling with the series 701. Intermediate connection faces use body-mounted close couplers without hooks.
- Obstacle deflectors reproduce the different inspection hatch locations between MOHA E721 and KUHA E720, and the presence or absence of inspection hatches varies by series.
- Front destination display set to Sendai; replacement front displays included: Shin-Shirakawa and blank. Destination decal stickers included.
- DCC friendly for modelers using digital control systems.
- Compatible with interior lighting kit Kato 11-211 (11-212)
