[PR] DART Battery Train Tender Issued

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

And we have been here before, https://www.independent.ie/life/flas...-34252634.html

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