Incident Investigation involves accident investigation including accident assessment, repair assessment and brake investigations on assignments such as depot derailments and collision damage. Transportation Information, Security and Surveillance systems are deployed throughout TfL’s transport network to enable the safe and efficient operation of TfL’s multi-modal capability and are commonly considered vital to the organisation’s capability to offer services to its customers. These systems ordinarily interact with travelling customers, operational personnel, operational control systems and third party systems and therefore require complex systems engineering and systems integration to result in expected high levels of function, usability, performance and availability. As demand for public transport rises TfL needs to augment passenger capacity to meet this ever increasing demand. This increase in capacity necessitates a greater degree of automation and communication facilities to monitor and control services, ensuring the public are able to feel secure in our stations and rolling stock while travelling efficiently. In order to do this engineered systems are required to be developed integrating railway assets, procedures and people. Following the recent government spending review, TfL continues to increase passenger capacity to meet ever increasing demand, and improve customer service across all modes. Our service is now more reliant on computer, communication, and software systems and the interconnectivity between electronic systems is increasing unabated. This includes the connectivity between systems within our organisation and interfaces to external networks (such as the internet and COTS-based wireless communication systems). To improve the delivery of transport services and enhance the customer experience there is a desire to obtain, communicate and utilise the information that is generated and used by our systems. To protect against safety threats, deliver services reliability and consistently, reduce costs through unnecessary reactive controls, mitigations and recoveries, and to restrict the reputational damage to TfL from undesirable actions or threats, the electronic security of systems and information is critically important to us. Communication networks are deployed throughout TfL’s transport networks to enable and support operations, maintenance and support services in wide range of geographic locations. Support is provided locally and at line and network control centres. Communications networks provide key interfaces and functions to TfL’s staff, customers and third parties. They facilitate normal, degraded and emergency mode of service operation but also interface with the emergency services during incidents. Systems engineering is an interdisciplinary approach and a mean to enable the delivery of systems that will meet the customer/user needs. It focuses on defining customer/user needs and requirements early in the development cycle systematically, documenting them, and then proceeding with design synthesis, implementation and system verification and validation while considering the complete problem, including operations, cost and schedule, performance, training, test, manufacturing and disposal. Systems engineering is a combination of various techniques that aims to manage engineering risk throughout the projects / programmes lifecycle by considering the problem as a whole rather than disparate parts. Information security engineering is a set of risk-based technical and procedural controls to minimise vulnerabilities of engineering systems to electronic (or cyber) threats throughout the asset lifecycle. In the TfL environments, particular systems are critical to the safe and reliable operation of the railway, such a road and rail signalling systems, SCADA, customer information systems and CCTV systems. Software systems are increasingly at the core of modern transport networks. TfL undertakes the following roles within the transport network: operator, specifier, intelligent client and overall integrator. In general, TfL prefers not to specify and procure bespoke software, due to the impacts of risk, time and cost. This strategy results in the need to leverage supplier’s products where necessary, with adaptation and modification for the particular transport application’s environment and needs. Managing the specification, development, test, migration and performance of (supplier) software is often critical to the successful delivery of transport projects and transport systems. System Performance Engineering aims to understand the behaviour of railway performance as a whole and how constituent parts interact. Modelling tool-sets are used to improve and optimise network capacity through the identification and mitigation of system constraints. In delivering this capability, TfL develops in-house software based engineering tools to allow for detailed understanding of the railway as a whole. TfL applies this engineering capability at different stages of the programme lifecycle to ensure the railway performs as intended, efficiently and effectively System safety engineering is the identification, understanding, management and control of safety hazards that originate from incorrect operation or use and that could harm the customers or staff of a transport system. The objective of System Safety Engineering is to demonstrate that the transport system is free from harm and that safety risks are managed to acceptable levels. SCADA is an acronym for Supervisory Control and Data Acquisition. SCADA systems are used to monitor and control plant or equipment in many applications such as telecommunications, electrical power control and railway transportation. The supplier will be expected to supply advice, studies, test procedures, analysis, reports, design and supervision services which will, in turn, rely and depend on skill, competence and capabilities including but not limited to the following capability details: The supplier shall demonstrate competence in: • SCADA requirements including legislation and standards, operational and maintenance requirements • Design, development and implementation of SCADA architectures; distributed, networked, cloud-based O Telecoms networks – LAN’s / WAN’s, fibre-based transmission, wireless O PLC’s/ RTU’s design applications in SCADA type plant/ environments O PLC/ RTU programming / ladder logic/ IEC 61131-3 O SCADA protocols – Modbus-TCP, Ethernet, TCP/IP, DNP3, IEEE 60870-5 O SCADA standards - IEEE 60870, IEEE C37.1-2007 • SCADA testing and commissioning • Preparing SCADA documentation • TfL Transport Networks including TfL Railway Environment domain Knowledge Knowledge and understanding of the SCADA systems, other assets, processes and roles that are used in the railway environments of London Underground, the Docklands Light Railway, London Overground and Croydon Tramlink. Electronics is equipment that contains circuit boards, circuitry and components that are used for transmitting or processing analogue and/or digital data. On the TfL estate this ranges from hand-drawn and built circuitry from the 1950s to modern microprocessor based systems with surface mount construction. TfL are seeking specialist support to undertake electronics design to support delivery and maintenance projects, primarily for signalling and fleet. The scale of this scope could be from a single design for one-off use through to design changes and upgrades that have network-wide implications. Electromagnetic compatibility is the understanding, management and control of electromagnetic interference arising from the emission of electromagnetic energy from systems and the impact of that phenomenon on other systems that are susceptible to it. The objective of EMC is to control emissions and susceptibility, so that adverse effects are avoided. Human Factors (HF) is the understanding of interactions between humans and other elements of a transport system, and the application of theory, principles, data and methods to the analysis and design of the transport system in order to optimise overall system performance through optimised human performance and well-being. TfL’s customers and stakeholders expect Transport Systems within London to be reliable and affordable. • Reliability is the probability that a system will continue to perform correctly to a particular time. • Availability is the ability of a system to be in a state to perform correctly at any time. • Maintainability is the probability that a maintenance action can be carried out within a stated time interval. Maintainability also includes the cost of planned maintenance activities required to support safe and reliable operation in service. The objective of RAM within TfL is to manage the reliability, availability and cost of transport networks so that the performance of these three parameters improves continuously and the adverse effects of any changes are avoided. • Assessment of track railborne and non railborne equipment for track renewals • Assessment of track railborne and non railborne equipment for track maintenance • Approval of track railborne and non railborne equipment • Standards including specifications • Strategy • Feasibility Design • Track Component design • Noise and Vibration • Wheel Rail Interface • Standards including specifications The supplier shall demonstrate their knowledge and ability to communicate with and advise their client in one or more of the following areas: • Signalling installation, testing and commissioning • Signalling maintenance & repair • Signalling audit and inspection • Incident investigation • Signalling asset management / asset performance • Point operating equipment • Remote condition monitoring • Risk based maintenance • Assurance activities for product and system acceptance • General technical support The supplier shall demonstrate their knowledge and ability to communicate with and advise their client in the following areas: • Signalling design process • Interfaces with a variety of equipment including, but not limited to, Point operating equipment, Passenger information systems, Remote condition monitoring. • Fixed block legacy signalling systems • Automatic Train Control (ATC) systems, including coded track and Communications Based Train Control (CBTC) systems that provide Automatic Train Operation (ATO) and Automatic Train Protection (ATP) • Automatic Train Supervision (ATS) systems • Assurance activities for product and system acceptance • General technical support The supplier shall demonstrate their knowledge and ability to communicate with and advise their client in the following areas: • Power SCADA specialism • AC Power Modelling and Studies (including DNO and National Grid infrastructure assessments) • DC Power Modelling • Train Simulation and Multi Train Simulation for Power System Modelling • Power Quality Studies (including DNO and National Grid infrastructure assessments) • Power System Reliability Modelling • Harmonic Profile Modelling (including DNO and National Grid infrastructure assessments) • AC Protection Studies • Asset Management deep technical support e.g. review of age profiles and specialist asset condition assessments • High Voltage specialist technical support e.g. Specialist advice and support on partial discharge monitoring and testing • Development of HV Power electrical design, including concept and detailed design • Earthing systems specialist advice and technical support • All aspects of DC Electrical Track Equipment (ETE) including conductor rail design • Overhead Line Equipment (OLE) design and maintenance
