Railway time
Railway time was the standardised time arrangement first applied by the Great Western Railway in England in November 1840, the first recorded occasion when different local mean times were synchronised and a single standard time applied. The key goals behind introducing railway time were to overcome the confusion caused by having non-uniform local times in each town and station stop along the expanding railway network and to reduce the incidence of accidents and near misses, which were becoming more frequent as the number of train journeys increased.
Railway time was progressively taken up by all railway companies in Great Britain over the following seven years. The schedules by which trains were organised and the time station clocks displayed were brought in line with the local mean time for London or "London Time", the time set at Greenwich by the Royal Observatory, which was already widely known as Greenwich Mean Time (GMT).
The development of railway networks in North America in the 1850s, India in around 1860, and in Europe, prompted the introduction of standard time influenced by geography, industrial development, and political governance.
The railway companies sometimes faced concerted resistance from local people who refused to adjust their public clocks to bring them into line with London Time. As a consequence, two different times would be displayed in the town and in use, with the station clocks and the times published in train timetables differing by several minutes from that on other clocks. Despite this early reluctance, railway time rapidly became adopted as the default time across the whole of Great Britain, although it took until 1880 for the government to legislate on the establishment of a single standard time and a single time zone for the country.
Some contemporary commentators referred to the influence of railway time on encouraging greater precision in daily tasks and the demand for punctuality.
Until the latter part of the 18th century, time was normally determined in each town by a local sundial. Solar time is calculated with reference to the relative position of the sun. This provided only an approximation as to time due to variations in orbits and had become unsuitable for day-to-day purposes. It was replaced by local mean time, which eliminated the variation due to seasonal differences and anomalies. It also took account of the longitude of a location and enabled a precise time to be applied.
Such new-found precision did not overcome a different problem: the differences between the local times of neighbouring towns. In Britain, local time differed by up to 20 minutes from that of London. For example, Oxford Time was 5 minutes behind Greenwich Time, Leeds Time 6 minutes behind, Carnforth 11 minutes behind, and Barrow almost 13 minutes behind. In India and North America, these differences could be 60 minutes or more. Almanacs containing tables were published and instructions attached to sundials to enable the differences between local times to be computed.
Before the arrival of the railways, journeys between the larger cities and towns could take many hours or days, and these differences could be dealt with by adjusting the hands of a watch periodically en route. In Britain, the coaching companies published schedules providing details of the corrections required. However, this variation in local times was large enough to present problems for the railway schedules. For instance, Leeds time was six minutes behind London, while Bristol was ten minutes behind; sunrise for towns to the east, such as Norwich, occurred several minutes ahead of London. It soon became apparent that even such small discrepancies in times caused confusion, disruption, or even accidents.
