During 1980, on two recently opened railway improvement schemes in Glasgow, passengers were interviewed about their journey, to discover where passengers new to rail travelled from, and the method of travel used before the opening of the new services. The argyle line added a new link to the British rail suburban network and tables and diagrams are presented to show the geographical location of trips diverting from bus and car. The survey estimated trips increased by 18 per cent, with the largest increases occurring for the more optional purposes of shopping and social activities. Generation of completely new trips was at most five per cent of weekday traffic, eight per cent on Saturday, being greatest for trips for social, recreational or "other" purpose. The Glasgow underground attracted 23 per cent of traffic from non-public transport modes or in the form of generated trips, with diversion from car occurring most often for shopping trips. Introduction of a multi-modal season ticket on British rail increased traffic by five per cent during the peak and four per cent off-peak. The main effect of a coordinated feeder-bus service on traffic at Drumchapel station was diversion of trips which would otherwise have used the through bus services to central Glasgow.
