From what I'm hearing, the next expansion is looking like Livingston next year, which would tie in with the rebranding from East Lothian to Lothian Country
Pure off-topic fantasy, I appreciate, but how would you tackle West Lothian (from an LB perspective)?
Twenty years ago, there were three corridors:
9: Edinburgh to Livingston like the SMT 27/28
64: Edinburgh - Gyle - Broxburn - Bathgate (similar to the SMT 16/17/18, but I don't think these served the Gyle?)
63: The Jewel - Edinburgh - Gyle - Broxburn - Pumpherston - Livingston (the eastern end being an attack on the Edinburgh Coach Lines 333)
...the 63 was later amended to follow the 64 route as far as Bathgate (but then to Whitburn?) - my memory is a little sketchy!
...but in those days there were no Edinburgh - Broxburn - Livingston daytime services (all Livi services ran via the A71 in the daytime), the train service to Livingston South/ Livingston North/ Bathgate was nothing like as good as today...
The "simple" option would probably be a decent frequency from Edinburgh to Livingston via Broxburn - maybe every fifteen minutes - diminishing marginal returns toward Fauldhouse/ Whitburn etc...
...or a "frequent" simple service from Livingston to Bathgate via the Hospital and Deans - the 21/26/27/28/800/X14 are fairly frequent on this general corridor, but there's not one simple frequent service (a bit like the way that First's simple frequent 22 from Rotherham to Barnsley found a market against the multitude of half hourly Stagecoach services in the Dearne Valley).
Which do you reckon would work better?
(pre-tram it'd have been better, could have interworked with the X48)
