/ Getting to Lochnagar/Dubh Loch by public transport
From Glasgow, I can't find anything that doesn't go via Aberdeen. Braemar does seem to be badly served by public transport compared to Aviemore.
Places alongside the A9 are bound to be better served by public transport (given that there is a choice of bus or train). Braemar is a small place - to be expected there's less options. There is a good bus service from Aberdeen up Deeside that stops in a number of places, including Ballater. If you took a bike, you could cycle from there up Glen Muick, which would be helpful for continiuing to the Dubh Loch. Alternatively, get off the bus at Crathie, and walk from there via Gelder Shiel.
Or you could get off at Invercauld and walk up to Lochnagar via the Ballochbuie pinewoods and The Stuic.
Maybe not the best approach for the NE coire however...
I don't think that it'll take much longer going by Aberdeen - driving back up from Glasgow it sometimes takes longer going via Braemar by enough of a margin you could be to Ballater in the time comfortably.
As alternative to other suggestions you could walk in from Balmoral and via the geldershiel bothy to the NE corrie.
Takes longer that from Glenmuick but definitely accessible by public transport. you'd have to walk over the top to get to Dubhloch though.
Easy enough to get to Ballater on the bus but need to go via Aberdeen. Get off, cross the bridge onto south deeside and then hitch a ride along the glen muick road. Would think that a climber would give you a lift at some point.
