Clock on The Exchange, Bristol, showing two minute hands, one for London time and one for Bristol time (GMT minus 11 minutes).. 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 detail found in Working Timetables includes the timings at every major station, junction, or other significant location along the train's journey (including additional minutes inserted to allow for such factors as engineering work or particular train performance characteristics), [2] which platforms are used at certain stations, and line codes where there is a choice of running line.
Greater speeds and the need for more accurate timings led to the introduction of standard railway time in Great Western Railway timetables in 1840, when all their trains were scheduled to "London time", i.e. Greenwich Mean Time (GMT), which replaced solar time. Until railway time was introduced, local times for London, Birmingham, Bristol and ...
A time–distance diagram is a chart with two axes: one for time, the other for location. The units on either axis depend on the type of project: time can be expressed in minutes (for overnight construction of railroad modification projects such as the installation of switches) or years (for large construction projects); the location can be (kilo)meters, or other distinct units (such as ...
The first combined railway timetable was produced by George Bradshaw in 1839. [2] His guide assembled timetables from the many private railway companies into one book. Bradshaw's continued to be published until 1961, with demand dwindling after the grouping of the railways in 1923, as each of the new "Big Four" companies published their own ...
Two F trains in the a.m. rush hour, and two in the p.m. rush hour, operate peak-direction express in Brooklyn between Jay Street and Church Avenue. [15] Every other J train is designated as a Z train during rush hours in the peak direction; both J & Z operate skip-stop between Sutphin Boulevard and Myrtle Avenue during these times. [17]
The cloth-bound book was entitled Bradshaw's Railway Time Tables and Assistant to Railway Travelling and cost sixpence. In 1840 the title was changed to Bradshaw's Railway Companion, and the price raised to one shilling. [4] A new volume was issued at occasional intervals and from time to time a supplement kept this up to date.
A copy of the 2002 edition of the National Routeing Guide. The railway network of Great Britain is operated with the aid of a number of documents, which have been sometimes termed "technical manuals", [1] because they are more detailed than the pocket-timetables which the public encounters every day.
