The remainder of passenger operations were non-Pullman, reflecting the ordinary business of running a passenger railway. West Country services were dominated by lucrative summer holiday traffic and passengers wishing to travel to the Isle of Wight and further afield. In winter months, the western extremity of the Southern Railway network saw very little local use, as the railway served sparsely populated communities. Competition with the GWR also diluted passenger traffic within this area, as this carried the bulk of passengers to the major urban centres of the West Country. Steam-hauled passenger services in the east of the network were gradually replaced with electric traction, especially around London's suburbs.
