This does not count vehicles! It only counts routes.
LOTHIAN ONLY:
There are 65 Lothian Routes in total (INCLUDING: Airport Routes, Night Routes and Express Routes) (EXCLUDING: Special Services, Lothiancountry, Eastcoastbuses)
There are 32 Lothian Routes in service during Lockdown (Including, excluding the same things)
that is about 49% of routes in service.
LOTHIAN, LOTHIANCOUNTRY AND EASTCOASTBUSES:
There are 90 Lothian, Ecb and LCB routes (INCLUDING: Airport Routes, Night Routes and Express Routes) (EXCLUDING: School Services)
There are 40 Lothian, Ecb and LCB routes in service during Lockdown (Including, excluding the same things)
that is about 44% of routes in service.
I would've also thought 25% however after doing checks its much more.
