There is enough to just get to Maynooth and back
BUT here is the stinker you cannot charge while stationary as the overhead wire would melt if you pulled more than about 150amps while stationary. Under full power each 2 coach pulls 500amps so to charge you would need to be able to support much higher currents
So you need a charging module to plug in using something other than the pantograph
The infrastructure to support this starts to get ugly, the wires are cheaper and simpler

How green is having to dig up several hundred tons of rare earth elements to make the batteries?
