Bill. Falkirk Grahamston is still there, as is Camelon. I think that there is a train running every thirty minutes between Edinburgh and Camelon with another two an hour between Edinburgh and Dunblane.
However, far be it for us to be responsible for rjhowie descending in to depression. Glasgow and Edinburgh are well served in terms of the number of routes, though the crown remains with the former NBR route between Edinburgh Waverley and Glasgow Queen Street via Falkirk High. Current best timings are 43 minutes for the 47 and a quarter miles with three stops (Haymarket, Falkirk High and Croy). Frequency is good, with around four trains an hour, two of which are the fast 43 minute services while another two take between 45 and 48 minutes with four stops (usually Haymarket, Linlithgow, Polmont and Falkirk High). The other lines are slower.
Edinburgh - Glasgow QS via Falkirk: 47.25 mi - 43 min, 3 stops.
Edinburgh - Glasgow QS via Falkirk Grahamston: 49.5 mi - 27 min, 2 stops to Grahamston, then Change trains (25 minute wait), then via Cumbernauld 46 min, 7 stops
Edinburgh - Glasgow QS via Airdrie: 44.25 mi - 66 min with 14 stops
Edinburgh - Glasgow C via Shotts: 47.25 mi - 75 min with 5 stops
Edinburgh - Glasgow C via Carstairs: 57.25 mi - 57 min, 1 stop (Cross Country trains services - irregular intervals and some 1 hour 2 stops) Stopping trains 74 min with 6 stops
The fast trains are via Falkirk High, so there is one high speed route with, to a degree, a second one via Carstairs to a much lower service frequency. The four routes other than via Falkirk High are slower with predominantly stopping trains providing access to either Glasgow or Edinburgh but when it comes to taking a share of the Edinburgh to Glasgow market they will be far behind the Falkirk High route in meeting demand.
