Livery variations

Sets P8 and P9 carried a "Mitsui Greenland" promotional livery, and set P11 carried a "Space World" promotional livery for a while. As of January 2013, P8 carries promotional vinyls for the Kyushu Heritage Museum, and the other two sets have been returned to the standard colour scheme.[5]

History

The first sets were delivered in June 1989, and entered service from 21 July 1989.[5] Trains became all no-smoking from 1 September 1995.[6]

11 811-100 series four-car sets were delivered from 1992, numbered PM101 to PM111.[5] These had a modified seating arrangement to provide more standing space in the doorway areas.[5]

Refurbishment

Refurbished set PM1504 in August 2017

In 2017, set PM4 was refurbished, renumbered as set PM1504. Refurbishment changes include replacing the traction control equipment with SiC-VVVF equipment, changing to a single-arm pantograph, tinted passenger windows, full-colour LED destination indicators, and replacement of the former transverse seating with longitudinal bench seating.[7] The interior and exterior design for refurbished trainsets was overseen by the industrial design company Don Design Associates.[8] The first refurbished trainset returned to service in April 2017.[8]
