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

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]
