Interesting to read about the reliability issues with these units, still this is nothing new. By the mid 1960s the new AM3 (later class 303) units for the Glasgow Suburban Electrification were considered the most complicated electric units of their time. Since their return to traffic following the major transformer issues that put them out of service for a year, further modification were needed in the quest for higher component reliability and longevity and eventually these mods ran into hundreds, (including the strengthening of the floor in the vestibules to combat the effects of stiletto heels). Investigations continued towards a reduction in down time, as at that time there was a diagramming provision for 19 units to be continually out of use for maintenance. This represented less than 79% availability.
It just shows that somehow lessons are never really learned....
