Why are the Ringsend EV's STILL restricted to just a few certain routes? They were new in 2007, we are nearly at the end of 2013 now and not one of them has strayed. The new GT's were only a couple of days into service and already they were out working the 27, 77A etc. It doesn't make sense to keep their EV1-8 batch still only used on the 1, 65/B and maybe 49 at this day and age.
