I feel that the 44 could be extended to Seafield it could either run along the same route then turn left past Eastfield, Joppa and Portobello up Seafield Road East and Seafield Road terminating at the same stop as the 1.
I can only see the above happening once the new houses have been built along Seafield Road East.
The Wallyford to Edinburgh section could be served by a new East Coast Buses route numbered something like 144.
It’s impossible at the moment but not necessarily in the future. Musselburgh is full though which is a problem that wouldn’t go away. So unless the 139/140/141 went back to Lothian as the 39/40/41 this idea is fairly unlikely to ever happen, or if enough drivers were sourced then a bigger use of Marine is unavoidable.
The most simple solution would be to give the Seton Sands corridor to ECB as a new route and reroute the 26 after Pinkie Road along the 44’s route to Wallyford/Whitecraig in my opinion. The Caravan Park could benefit from a faster bus to town, especially when it’s busy in the summer months. Haymarket to Seton Sands limited stop via Milton Road just like the others. Call it a 129. This would solve the excessive amount of buses along the Prestonpans-Seton Sands corridor if it was every 15 minutes. If you put the 113, 124 and 129 together you should be able to have a fast bus every 7-8 minutes from Musselburgh to Edinburgh. The X26 removed with the 129 serving Port Seton and presumably Blindwells in the peaks while still serving the Caravan Park.
You’d need an N129 to replace the N26 as well. So I’d suggest adding in an N19 from Granton to Eastfield to part replace the N26, giving Lochend a night bus again with this serving Craigentinny Avenue instead of Wakefield Avenue. In turn scrapping the N14. The N19 could be hourly and when combined with the N37 offers a half hourly service along Crewe Road South. Both the 129 and N129 would serve Pinkie Road.
The 4 would need to go up to every 15 minutes to plug the gaps left by the 44’s removal, as would the 34. It would also need to serve Willowbrae Road as those stops would otherwise be unserved. Only one set of stops on Northfield Broadway is effectively unserved though as the first set of stops are so close to the stops on Willowbrae Road anyway. Those at Northfield Square might be a bit annoyed though.
I’d then be looking at turning the 44 into an X44 running Balerno to Waterloo Place via West Approach Road. All stops Balerno to Slateford Station then only stopping at Shandon Place then Fountainpark and then all recognised stops (same as X27/X28) after that. This route could probably suffice as every 15 minutes.
All of a sudden this idea is a lot of changes just to remove the 44. I’m not against this plan, but for the travelling public it’s pretty complex.
I don't think a new route needs to be created exactly, maybe just reroute the 113 via Pinkie Road and Macbeth Moir Road and the do the N113 route via Wallyford covering Fa'side Avenue and Masons Way.
All areas covered and then you've got no need for the 44 beyond Edinburgh.
That would mean replacing an every 10 minutes service with one that is half hourly? Good idea in terms of routing, but inadequate on all other counts.
