Normally about 20 minutes more, but that is with a reversal so it could be a little as 5 minutes penalty if a cord existed and the trains could carry on a reasonable speed over it (and rejoining at Winchburgh). The line speed would also need to be raised on the Winchburgh branch.
They're not going to make trains reverse at Dalmeny! As for it taking five minutes longer, you do realise that via the Dalmeny Chord, it's almost a mile shorter than via Newbridge Junction?
If the sole point of this work is for a stop at Gogar it is a total waste of money as no-one benefits.
It's not.
If the work will provide a stop at Winchburgh then this is a good thing.
Winchburgh Station is not dependant on EGIP and AFAIA, it's not committed.
I am not sure if an Electric diversion route is that important now considering that you now have 2 alternative routes to Glasgow so DMU's could cope with Linlithgow, Polmont, Falkirk and Croy if a diversion is needed.
It's not a diversionary route, although it does provide that. Plus, ScotRail wouldn't have DMUs available to run a diesel service between Edinburgh and Glasgow as the units would have been replaced by EMUs.
I don't know the ins and outs of what is currently being designed, but I think that there are a number of members on scot-rail who have been involved.

I think that won't happen any time soon. I remember it as about Phase 4 of the plan. Which is unfortunate, as it is unlikely at present to take substantial traffic off the roads; even with its newish 'express' services', the journey time from West Lothian to GLC is longer than the A-B line's planned times.
STPR proposed phasing:
Phase 1 is EGIP; Phase 2 is the rest of the Central Belt (mostly
Glasgow and West of Scotland); Phase 3 is Edinburgh to Perth and
Dundee; Phase 4 is Dunblane to Aberdeen; Phase 5 is Perth to
Inverness. So, by the time you get to Phase 4, some of the route has
already been electrified.
