I think the fact that the 75 and 18 are getting new buses says a lot about the profitability of these routes. Probably First Glasgow’s best performing double-decker routes? So, yes, it makes sense to launch them on the 75.
The 38 could do with something better, but I’d like to see them try and simplify the route too. How First could launch something called Simplicity with a 38, 38a, 38b, 38c and 38e without blushing is beyond me.
The 38/38A should be left as is considering they start/finish in the same place, the 38C could work as the 36, a 36 used to be the number that went to chryston a few years back, this would make sense.
The 38E > 35 and 38B > 37.
The 35, 36 and 37 are numbers that dont exist atm at FiG as I’m aware.
Consider the 1B, the 1B could have its “B” removed and be the dedicated 1 service to Helensburgh bus.
Move the Balloch buses, 1/1A/1E > 2/2A/2B.
The 1D and 1C change there numbers as well, theres plenty of numbers to choose from, the 1C goes up through drumchapel, no where near balloch anyways.
And yes! I understand the existing 2 route numbering, faifley to Baillieston prevents that, but simply rename the 2 as say the 200 or Something and you’d be “cooking with buses”
