For the EMUs you have the 8100 class LHB DARTs delivered in 1983. There were 40 2 cars sets, each set had one 8100 power car coupled to an 8300 trailer car. Sets were numbered 8101/8301-8140/8340. Sets 10 and 37 were destroyed by fire in Fairview Depot in 2000.
Alstom DART units were bought to replace them and increase capacity in 1999. There were just 5 2 cars sets. 8200 power car and 8400 trailer car in each set. They very not operationally compatible with the older 8100 class but could haul them for maintenance. They generally worked in multiple with the 8500 and 8510 class delivered later on to form mixed 6 car sets as platforms were not long enough for 8 car formations of 8500 units at the time.
