I'm surprised that it's the 275 that is being axed, i would've expected the 276 to go instead. These changes do generally leave the West Lothian network quite bare compared to how it was and there's a few corridors that Lothian had attacked in the past that they're clearly not going for anymore. Notably Livingston - Broxburn and Livingston - Blackburn.
Glad to see the return of the X5 and the increasing in frequency of the 30, the cuts to the 22 also come as no surprise. If anything i won't be surprised if further down the line the 22 gets axed entirely and other services along the same corridors (such as the 1 and 2) get a slight increase in it's place or a new route is created instead. Once the tram extension is open running the 22 as it is from the Gyle Centre to Ocean Terminal really won't make much sense at all.
I know this will be controversial but there needs to a massive overhaul of the routes in general. Change the mindset that one bus can take me from penicuik to silverknowes for instance. The routes were designed from a different time when congestion wasn't an issue. Remove the barrier to switching between buses with a transfer ticket. Smaller buses to serve estates that connect with high frequency buses on the arterial routes. Less duplication of services on the arterial routes.
I agree, i also think there needs to be more cohesion between services where they share corridors. Just look at the 37 and 47 for example, in most other cities these routes would be combined to some extent as different variations of the same service and would be timed consistently. Instead at present you have a 37 operating up to a 15 minute frequency and a 47 operating up to every 20 minutes.
Another example is the western legs of the 26 and 31, both routes operate every 12 minutes and are timed to provide a 6 minute frequency over the shared sections of route, this is really something that should be advertised, yet it isn't. In fact in the past i have found that lots of people don't even realise you can get the 31 to the Zoo!
I actually think both examples listed highlight cases where route branding could actually be very beneficial. I'm not saying they're perfect examples or how Lothian should follow but just look at what First Glasgow did with The One or the 38, they brought multiple existing routes under one brand that provide a consistent high frequency over a shared corridor.
