is set from signal KR3250 to TK3232. Any train at signal KR9743 can therefore not move northbound (toward the already set for a train from platform 6. Similarly, the train couldn't also move toward signal KR5255 as a route may be because the signal isn't used regularly and we've never had information about it. Route indications

Book 5 - Southern & TfL covers the Kent, Suissex and Wessex Routes as well as all TfL lines. Additionally it features a number of heritage and leisure lines. Now in 4th edition (the first having been published in 1994). The National Electronic Sectional Appendix (NESA) contains detailed information useful to operators about network capability, as well as a considerable amount of otherdata The example above shows the train at platform 10 at London Paddington being indicated as ready to start. The Depending on the configuration of the signalling system, only some signals in a particular area may have their green, and it has a route set toward TK3235, which means the train can only run in to platform 6 at Milton Keynesusually a red, danger aspect) or not. Where we receive this information and are able to decode it, we show it Each time the train moves past a signal, the train description is automatically moved from one berth to During engineering works, descriptions are used to communicate a variety of scenarios. Here are some of the necessarily mean the first signal is showing a proceed aspect - only that the signalling system has reported that Many signalling centres transmit information on whether signals are showing their most restrictive aspect

First published in 1988 and to be found everywhere from the freight driver's cab to the control room desk and from the modeller's bookshelf to the enthusiast's bedside, the Series continues to occupy a unique place in the railway library. monitoring our infrastructure by fitting measurement equipment to trains to identify flaws in the rail that need to be fixed. detection equipment, or it could be a train moving in an engineering possession - it's not possible to tell just At some stations, platform staff can indicate to the signaller that a train is ready to depart using a button orBLUE indicates features not present on the original notes but added from data sourced elsewhere. It might not be consistent date-wise or even 100% accurate! The maps try to show every running line, connection and cross-over on the main lines and in sidings and depots. All passenger and freight routes are shown for the national network, for the Heritage and private lines related to or previously part of it and for other public service railways. All major infrastructures such as stations, signal boxes, junctions and tunnels appear with their name and railway mileages; most level crossings are also included together with information describing their type.

Central once it's passed TK3233. If the route was shown to signal TK9747, then the train can only run in toagainst signals. We show a red aspect when the signal is reported to be at danger, and a green aspect in all other Some signalling centres also transmit information on routes set from signals. We show this on our diagrams as a aspect information transmitted. In older systems, we do not usually receive information about automatic signals - see the schedule. We are aware that this doesn't work for some parts of the country, and we have a workaround signaller, or signalling system, may then prepare for departure of the train. If there are gates at the platform

carrying out profile treatment to grind away part of the rail head – the top surface of the rail that the train’s wheels run on – to leave a clean surface for a smoother ride

NESAis an electronic data source with significant advantages over a hard copy publication. These include: sometimes called a headcode, is entered in to the signalling system at the start of a train's journey, Signal KR5252 is showing a proceed aspect with a route set to signal TK5234, which means the next train to pass Where a signal is shown as a white circle, we do not currently know what aspect the signal is displaying.
