s on the vehicles or stations inducing currents in the loop that can be read at a distant location. In the case of SelTrac, the central computer sent data to the vehicles at 1200 bit/s on a 36 kHz carrier while the vehicles had 600 bit/s on a 56 kHz carrier. Separate pair of antennas is used for transmission and another pair is used for reception. The two-wire inductive loop system was prone to vandalism and, in newer versions of SelTrac, the control signal is transmitted inside the running rails at

Position keeping

SelTrac uses the twisted-loop concept developed by

Siemens Siemens AG ( ) is a German multinational conglomerate corporation and the largest industrial manufacturing company in Europe headquartered in Munich with branch offices abroad. The principal divisions of the corporation are ''Industry'', '' ...

in the 1950s. SelTrac's loops cross every 25 meters to form lozenge-shaped areas. The communications system on the vehicles can detect a phase change in the signal caused by these crossover points, allowing them to place themselves within a single one of these sub-loops. Position within the loop can be further measured by counting axle revolutions. The vehicles broadcast this position information into the loops, along with IDs, speed, direction and other data. This system is not accurate enough for positioning within a station. Further accuracy is provided by "station alignment boards" which the train attempts to capture directly beside a sensor. When approaching a station, the vehicle is slowed to allow the board to be captured by the onboard sensors, and the vehicle automatically brakes to a stop at a constant speed when it is seen. If the train passes the board, due to ice on the rails for instance, the train has to be manually reversed to capture it again. The stopping position of the train is especially important when the platform doors are used. Both sets of doors, train doors and platform doors must be precisely aligned, with just a few cm tolerance, to avoid the obstruction for passengers (specifically on wheelchairs). Platform doors are widely used on stations with expected large crowds of passengers such as in Shanghai Metro, Mekkah, Dubai and others.

Traffic control

In traditional train control, the railway is split into control "blocks" with signals in each one. Blocks are sized to allow the heaviest or fastest trains to stop fully within them. That way if a train is stopped in the next block, the following train will always have time to fully stop before reaching it. Careful tuning of block spacing is needed; if they are signals that are placed too close from each other, train speeds have to be reduced so they can still stop in time, but spacing them out further means the trains are also spread out and the route capacity drops. SelTrac automatically maintains

headway Headway is the distance or duration between vehicles in a transit system measured in space or time. The ''minimum headway'' is the shortest such distance or time achievable by a system without a reduction in the speed of vehicles. The precise defi ...

system. In this system the start and end points of the blocks are not fixed, and move along with the trains. This allows the central control system to calculate a point on the track where every train can safely move without further instruction—in a fixed block system this would be the next set of signals, but with SelTrac it is constantly being updated. In theory this system could eliminate the "brick wall" criterion and allow the trains to run as close together as the communications speed would allow, but in practice a further spacing is typically imposed (for instance 50 m in the case of the

When originally being designed, computers were expensive and data storage was limited. In keeping with this model, the original SelTrac used on the ICTS

controllers. These now know the layout of the track, speed limits and various other data. This allows the controllers to make much better decisions about setting their speed—speeding up before an incline for instance.

Product family

SelTrac is offered in two ways: 1. A complete integrated solution in which movement authority and interlocking are integrated within wayside zone controllers; this reduces equipment and potential interfacing issues. Integrating the management of the interlocking with train location information, as communicated through the CBTC system, allows faster response times, more tightly controlled movements, and easier expandability and adaptability. Interfaces within the zone controller are more easily designed than those between subsystems. The integrated system knows the position of each train to a high degree of accuracy. It can control the behavior of the train at all times and, in response to changing conditions, can modify the behavior to ensure safety of the system while offering maximum service. It can adapt its algorithms to take advantage of individual train behavior, and change parameters to ensure optimum use of resources, such as platform availability and traction power. The limit of movement authority setting logic has a high impact on the end system performance, i.e. managing the interlocking in an integrated manner. Interlocking and switch control logic is optimized using position reports of communicating trains. The integrated design includes: * Unattended and driverless train operation and cab-signalling modes * Moving-block technology * Automatic performance modification * Fully redundant train to wayside configurations * Data communication option (loop or radio) * Automatic route setting * Quick-start reset * Solid-state interlocking and remote point machine control * Automatic coupling/uncoupling 2. A 'progressive' overlay solution: (a) Speed and signal safeguard: it vitally supervises speed profiles and signal adherence and provides all the functions of an intermittent ATP (automatic train protection) (b) Continuous automatic train protection: provides the added value of improved headway while maintaining safe train separation, without depending on axle counters or track circuits. The system will automatically generate movement authorities based on actual locations of moving and fixed obstacles. It is used in conjunction with external interlockings and provides a replacement for automatic separation signals between interlockings. It can operate seamlessly with existing track circuits, which provides an inherent mechanism to operate mixed-mode traffic. (c) Automatic train operation (ATO) offering automatic train movement allowing a driver to operate "hands-off" and thereby improve running performance. Moving to fully automatic operation (FAO) provides an excellent means to match train supply to passenger demand.

Data communication is provided with either low frequency inductive loop or a high bandwidth, open-standards wireless system incorporating spread-spectrum radio technology.
