It was when the 2700s were pushed into regular service on the Connolly to Rosslare route as the 071+Mk2Ds were being phased out when alot of the 2700 problems were brought to the fore front. One 6 car formation even split when in service. The 2800s were a big improvement on this route and really showed how unsuited the 2700s were. There were times when the 2800 fleet were producing 100% fleet availability with all 20 cars in service for weeks on end while working Northern commuter, Maynooth and Rosslare services out of Dublin with no issues. The polar opposite of the 2700s.
