So it seems that what you really want is something that uses more units to create a slightly better service for your journey specifically, and you think that complaining about the current service "wasting" units is a sensible way to achiave that? OK!
In terms of wasting units I was referring to the fact this new service was created in December and uses more units. The other service was just a seperate suggestion.
Presumably there is a plan for those units and which routes they will be on so you proposing:
Removing planned usage of 385s from routes somewhere (strengthening Cathcart?, 3tph Shotts? somewhere else?)
Reducing Grahamston - Cumbernauld from 2tph to 1tph
Removing direct Springburn, Robroyston, Stepps, Gartcosh, Greenfaulds, Cumbernauld - Edinburgh services completely.
And the benefit is:
Linlithgow / Polmont - Stirling customers don't have to change (but Linlithgow / Polmont - Bridge of Allan / Dunblane still do)
2tph extra slow services for Larbert / Stirling - Edinburgh (that may not be much faster than waiting for the next semi fast service)
I'd want to see some demand figures for Linlithgow - Stirling journeys to show that they attract more passengers than all the opportunities lost from the above changes.
On the first point, there’s not evidence an extra service (one or two extra units extra maximum) would reduce any other service given the number of 385s involved.
On the second point, Grahamston-Cumbernauld managed just fine with 1tph for years and didn’t suffer from any overcrowding. Given the numbers between all of those stations (between Springburn & Cumbernauld) to Edinburgh, it wouldn’t change much.
On the third point, the benefits obviously don’t stand out as huge, but neither did (or still do) the benefits for the E-G via Cumbernauld. The passenger numbers are very low as any user of the service will tell you, and at least using the paths/units on a different (more proven and actually used) route would help to reduce congestion and reinstate direct links.
As for Lin/Pol passengers still having to change for BofA/Dunblane, I did this as I cannot see capacity (or demand) to have 4tph turn around in Dunblane, and I decided to leave them with the ‘faster’ service. As for your last point, it’s not just ‘Linlithgow-Stirling’, you see people from Linlithgow & Polmont get off at Grahamston going North, and waiting. You also see people from Larbert & Stirling getting off at Grahamston going South, and waiting. You only have to take a ride on one of these trains.
I can guarantee you that such a service would be far more used than the current E-G via Cumbernauld.
