Formations

The 5000 series trains are formed as six-car sets as shown below.


Interior

Passenger accommodation consists of longitudinal bench seating throughout, with a wheelchair space in each car. The first 17 sets use LCD destination indicators; the 18th to 20th sets use LCD displays as destination indicators.


History

Built in 1995 to combat issues of platform congestion, the first 5000 series set was introduced onto the line in October 1995; a total of 17 sets were introduced from 1995 to 1999, ultimately replacing all of the 2000 series sets in service. Three more sets were introduced from 2009 to 2011 to replace the last remaining 3000 series sets at the time.
