WebTyer's Electric Train Tablet system is a form of railway signalling for single line railways used in several countries; it was first devised in Great Britain by engineer Edward Tyer after the Thorpe rail accident of 1874, which left 21 people dead. [1] It was used in New Zealand for close to 100 years until June 1994.

WebJun 6, 2014 · Block: A section of track on a layout that is electrically isolated from adjoining sections by use of plastic rail joiners or gaps cut in rails. Blocks can be any length – usually determined by a specific track plan. Block switch: A single-pole double-throw (SPDT) electrical switch that’s used to connect one wire to either of two other wires. Webblock system: [noun] a system of mountain ranges composed of tilted or uplifted fault blocks — compare basin range.
Automatic block signaling (ABS), spelled automatic block signalling or called track circuit block (TCB ) in the UK, is a railroad communications system that consists of a series of signals that divide a railway line into a series of sections, called blocks. The system controls the movement of trains between the blocks using automatic signals. ABS operation is designed to allow trains operating i… WebWestinghouse Rail Systems Ltd and Dimertronic Signals have developed TBS100, a transmission-based train control system that can operate in three modes: speed signalling, distance-to-go (DTG) or moving block. ...

In this system, different from the conventional railway systems, there are access points near the railway and ... WebThe block section is usually taken to be the section of track from the most advanced signal controlled by the station in the rear (usually the starter or advanced starter signal), and the rearmost signal controlled by the station ahead (usually the home or outer home signal).
Block systems are used to control trains between stations and yards, but not normally within the yards, where some other method is used. Any block system is defined by its associated physical equipment and by the application of a relevant set of rules. Some systems involve the use of signals while others do … See more Signalling block systems enable the safe and efficient operation of railways by preventing collisions between trains. The basic principle is that a track is broken up into a series of sections or "blocks". Only one train may … See more The basic problem for train control is inability to change course and the relatively long stopping distances of a loaded train. This is … See more The first use of block working was probably in 1839 when a Cooke and Wheatstone telegraph was installed in the Clay Cross Tunnel of the North Midland Railway. The telegraph instruments were replaced in 1841 with ones specific to block working. In … See more Strict timetable operation Most rail routes have a sort of natural block layout inherent in the layout of the railway stations. This provides the ability to implement a set of blocks using manual signalling based at these locations.
