Might be an issue, but PMO directly looks into its progress every month. Things will be done at all costs.It will be an issue and its a genuine one. Maharashtra needs to spend equal share as of Gujrat. But Gujrat gets all of its major cities and industrial region connected while Maharashtra gets only Mumbai. Its a bit unfair.
Semi High Speed is not the no1 priority. 100% electrification is. Gauge conversion and electrification status is also directly checked by PMO every month.
As and when WDFC and EDFC gets operational, Railways will be able to do funding for upgrade to semi high speed for trunk routes to and from Delhi initially. By that time the Southern railway boards have been directed to patch up their non electrified regions. As and when that happens, they will start receiving newer under development MEMU train sets to replace all the under 6hr trains. And dual headed WAP5 might find their way too.
