 With the transfer of routes of the North Western Road Car Company within Greater Manchester to the local Passenger Transport Executive in 1971, NBC split the residual services of NWRCC between Trent and Crosville, with the latter company taking over 119 vehicles and depots in Northwich, Macclesfield and Biddulph in March 1972.A consolidation of companies within NBC resulted in Crosville taking over services in parts of West Wales from Western Welsh, including those from the depots in New Quay, Newcastle Emlyn and Lampeter.The company continued to consolidate and reduce its network through the 1980s, making losses of £1M in 1980 and £2M in 1981.
