Renfrewshire extends to the south-west of Glasgow and along the south bank of the River Clyde, including the towns of Renfrew, Paisley, Johnstone, Erskine and Houston as well as the Erskine Bridge over the Clyde and Glasgow International Airport at Abbotsinch. The presence of the airport as well as a large population commuting to work in Glasgow means Renfrewshire supports one of the busiest transport infrastructures in Scotland.In this book, David Devoy, author of such titles as Ayrshire Buses and Western SMT Buses, takes a look at the independent bus operators in Renfrewshire.
