ETCS Level 2
The European Train Control System (ETCS) is the signalling and control component of the European Rail Traffic Management System (ERTMS). It is a replacement for legacy train protection systems and designed to replace the many incompatible safety systems currently used by European railways. The standard was also adopted outside Europe and is an option for worldwide application. In technical terms it is a type of positive train control (PTC). ETCS is implemented with standard trackside equipment and unified controlling equipment within the train cab. In its advanced form, all lineside information is passed to the driver wirelessly inside the cab, removing the need for lineside signals watched by the driver. This will give the foundation for a later to be defined automatic train operation. Trackside equipment aims to exchange information with the vehicle for safely supervising train circulation. The information exchanged between track and trains can be either continuous or int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Operating Company
A train operating company (TOC) is a business operating passenger trains on the railway system of Great Britain under the collective National Rail brand. TOCs have existed since the privatisation of the network under the Railways Act 1993. There are two types of TOC: most hold franchises let by the Department for Transport through a tendering system, to operate services on certain routes for a specified duration, while a small number of open-access operators hold licences to provide supplementary services on chosen routes. These operators can run services for the duration of the licence validity. The franchised operators have changed considerably since privatisation: previous franchises have been divided, merged, re-let to new operators, or renamed. Some operators have been taken over by a government-owned operator of last resort, due either to failing expectations or to events on the rail system as a whole. The term is also sometimes used to describe companies operating pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invensys
Invensys Ltd. was a multinational engineering and information technology company headquartered in London, United Kingdom. It was formed in 1999 through the merger of BTR plc and Siebe plc. It had offices in more than 50 countries and its products were sold in around 180 countries. The company was founded on 1 April 1920 as Siebe Gorman & Company Ltd and continued through various name changes registered at Companies House from that date.

Baseline (configuration Management)
In Configuration Management, a baseline is an agreed description of the attributes of a product, at a point in time, which serves as a basis for defining change. A change is a movement from this baseline state to a next state. The identification of significant changes from the baseline state is the central purpose of baseline identification.CMMI Product Team, "Chpt 7, Maturity Level 2: Managed, Configuration Management, SP 1.3," in ''Capability Maturity Model Integration, Version 1.1 (CMMI-SE/SW/IPPD/SS, V1.1): Staged Representation,'' Carnegie Mellon Software Engineering Institute. Typically, significant states are those that receive a formal approval status, either explicitly or implicitly. An approval status may be attributed to individual items, when a prior definition for that status has been established by project leaders, or signified by mere association to a particular established baseline. Nevertheless, this approval status is usually recognized publicly. A baseline ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System Requirements Specification
A System Requirements Specification (SyRS) (abbreviated SysRS when need to be distinct from a software requirements specification (SRS)) is a structured collection of information that embodies the requirements of a system. A business analyst (BA), sometimes titled system analyst, is responsible for analyzing the business needs of their clients and stakeholders to help identify business problems and propose solutions. Within the systems development life cycle domain, the BA typically performs a liaison function between the business side of an enterprise and the information technology department or external service providers.

Trans-European High-speed Rail Network
The Trans-European high-speed rail network (TEN-R), together with the Trans-European conventional rail network, make up the Trans-European Rail network, which in turn is one of a number of the European Union's Trans-European transport networks (TEN-T). It was defined by the Council Directive 96/48/EC of 23 July 1996. The European Union council decision 2002/735/EC defines technical standards for interoperability of the system. Description The aim of this EU Directive is to achieve the interoperability of the European high-speed train network at the various stages of its design, construction and operation. The network is defined as a system consisting of a set of infrastructures, fixed installations, logistic equipment and rolling stock. By definition of the EC decision, a high-speed line must have one of these three infrastructure characteristics: * specially built high-speed lines equipped for speeds generally equal to or greater than 250 km/h * specially upgraded high-s ...

Railway Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a rolling stock, railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era.

Loading Gauge
A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Classification systems vary between different countries, and gauges may vary across a network, even if the track gauge is uniform. The term loading gauge can also be applied to the maximum size of road vehicles in relation to tunnels, overpasses and bridges, and doors into automobile repair shops, bus garages, filling stations, residential garages, multi-storey car parks and warehouses. A related but separate gauge is the structure gauge, which sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. The difference between these two gauges is called the clearance. The specified amount of clearance makes allowance for wobbling o ...

Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by ...
