My prediction come the next changes is that in further retaliation to First the EX1 will be scrapped. The X17 and X18 may see some changes to tighten them up and possibly something going via Kirkliston. The EX2 possibly being extended to Falkirk or even Stirling (uni in the peaks), starting from Regent Road, St Andrew Square, George Street, Charlotte Square, Lothian Road and The Exchange, then back on to normal route.
Read online that apparently there are more of those daft interurbans on order, not sure if this is the case but it wouldn't surprise me. If this is the case we may even see interurbans on off-peak and extra X17's / X18's.
If the LC network is tightened up and weekly, monthly and possibly even yearly ticketing options are available then the West Lothian area could start getting interesting.
Once the management and union issues begin to calm down, driver morale and driver count across the brands picks up the company could see themselves in a better position.
I dont personally think the 43 moving to Livingston is a good idea, if possible it would be best based at Central or Longstone with facilities for LC drivers in these positions. If the 43 was based at Longstone, so could the 275, meaning early/late duties could be managed easier.
