6 6.1 Appendix Technical appendix Appendix Questionnaires are handed out at stations to passengers about to board a train, with a reply-paid envelope provided for returning questionnaires. Each train operating company (TOC) is sampled separately. Interviewers are generally given a number of questionnaires to hand out at a station. At Gatwick and Heathrow Airports, and for some shifts at certain London termini, questionnaires are handed out to passengers of a specific TOC. From Autumn 2003 onwards, at all other stations, questionnaires were handed out to passengers of any TOC (in the past all TOCs were targeted). The number of questionnaires handed out will depend on three main factors: the size of the station, time of day, and the length of shift. On Arriva Trains Wales and London Overground and one route on both ScotRail and South West Trains, most NPS shifts are done on-train. These TOCs routes operate in either mostly rural areas or in areas where there are a lot of small or relatively small stations where it is efficient to do most NPS shifts on-train. On First Hull Trains, Grand Central, Heathrow Connect and Heathrow Express most questionnaires are handed out on the train to ensure return of sufficient questionnaires. Approximately 32 per cent of questionnaires that are given out are returned. Returned questionnaires are checked to confirm that details provided are for a real journey and then the questionnaire response is assigned to the appropriate TOC. TOC data is compiled to provide a national sample. Fieldwork is carried out each spring (principally in February/ March) and in the autumn (principally in September/October). Up to spring 2003, fieldwork took place over three weeks. From autumn 2003, the fieldwork was extended to a 10 or 11-week period to provide a better representation of journeys (though if Easter is early, the fieldwork period may be slightly shorter and start earlier than normal). Quotas for returned questionnaires are set overall and by weekday/weekend, journey purpose and station size. All data for a TOC presented in this report is weighted up to the number of passenger journeys annually on the TOC and the profile of these journeys by weekday/ weekend, journey purpose (commuter, business, leisure) and station size. The data for number of journeys and profiles by these variables has been collected and updated from TOCs periodically since the survey started in autumn 1999. Most recently this was done prior to the Spring 2013 survey. The stations for each TOC were stratified by the number of passengers and a number of stations in each size stratum is sampled. This sample design and weighting ensures that data is representative of all passenger journeys made on each TOC. National results are constructed by combining data for all TOCs together, weighting by number of journeys. To allow simple reprocessing of data in line with changes to franchise boundaries, the sample design for NPS utilises a ‘building block’ approach from autumn 2003 onwards. For some of the new franchised TOCs it is not possible to provide reliable data pre-autumn 2003. For the autumn 2007, spring 2012 and autumn 2012 fieldwork, a small number of shifts were moved from the morning peak to the evening peak. In spring 2013 a small number of shifts were moved from the evening peak to the morning peak. In autumn 2007 shifts were also staggered for the first time so that they started every hour as opposed to every three hours. For example, morning shifts that were previously 7am-10am and then 10am-1pm were changed to 7am-10am, 8am-11am, 9am-12noon, etc. These changes give a better representation of passenger opinions of their journey.
