That's over a fairly long time frame. Sure, Milton deserves to be in the mix.... but do you want the existing projects to proceed more slowly so some of the money available flows to Milton (and not getting that job done all that quickly, given that smaller slice) ? Better to get the already-committed projects moving and complete as fast as humanly possible and then more of the cash flow can be directed to Milton.
The saving grace is that once some of the RER lines do achieve that 2WAD performance, the public pressure to add the Milton line to the system will be that much greater. If any of the existing politicians are still around, they will feel the heat from that.
