History
The first sets were delivered in June 1989, and entered service from 21 July 1989. Trains became all no-smoking from 1 September 1995.
11 811-100 series four-car sets were delivered from 1992, numbered PM101 to PM111. These had a modified seating arrangement to provide more standing space in the doorway areas.
Refurbishment
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. The interior and exterior design for refurbished trainsets was overseen by the industrial design company Don Design Associates. The first refurbished trainset returned to service in April 2017.
