thanks! :)
first things first -- no new AC services to be introduced with the induction of second AC rake. First one will undergo overhaul, and may be some additions.
secondly, for the thoroughly vestibuled AC EMU, we may get to test performance against enhanced carrying capacity. which may again initiate need for more power.
thirdly, i need to get some details, as to...
more...

whether there will be just ordinary second and AC or first is also clubbed in.
fourthly, is there a scope for additional space for vendors, disabled and seniors or is it being removed in semi AC rake too.
It mentions automatic door closing for only 6 coaches, but those have to be AC to need them. they say there'll be 6 MCs as opposed to 4 in present EMUs. this area needs to be explored. let the trials run and we'll find out. importantly, all will know exactly only after a week or more of live trials.
