Access dispute resolution rules: Rules which govern the handling of rail disputes arising from matters covered by the Network Code.
The term 'alliances' is currently being used to describe a wide range of different relationships from project-based partnerships through to potentially long-term and comprehensive commercial arrangements covering a wide range of activities carried out by Network Rail routes and train operators. The common factor is that Network Rail and a train operator reach agreement to work together more closely and share the benefits of doing so, within the framework of their existing individual accountabilities and responsibilities. As currently being discussed, alliances do not involve the creation of new legal entities such as formal joint ventures.
Network Rail is required, as a railway licence holder, to develop and apply the policies and criteria it will apply in respect of the maintenance, renewal, replacement, improvement, enhancement and development of the relevant railway assets, and make appropriate information about those policies and criteria readily accessible to persons providing services relating to railways and funders.
The company is also required to maintain appropriate, accurate and readily accessible information about the relevant assets, including their condition, capability and capacity.
Effective asset management supports the delivery of this promise by planning, delivering and making available an infrastructure that supports the current and future timetable safely, efficiently and sustainably.
Railway assets include: tracks, signals, tunnels, bridges, viaducts, level crossings and stations.
The Association of Train Operating Companies (ATOC) is an incorporated association owned by its members. It was set up by the train operating companies, formed during privatisation of the railways under the Railways Act 1993.
As well as being the official voice of the passenger rail industry, it also provides its members with a range of services that enable them to comply with conditions laid on them in their franchise agreements and operating licences. These include the National Rail Enquiry Service (NRES) and Railcard marketing.
ATOC's principal activities include assisting members to co-operate on developing and managing projects that benefit passengers and to promote the advantages of the rail network.

Freight recovery board
The freight recovery board was set up in line with our enforcement order in January 2012, with the purpose of promoting improvements to freight service performance (reducing delays to freight services) and protecting the interests of freight customers. The remit of the freight recovery board was to agree reasonably practicable steps Network Rail should take to remedy the licence breach of condition 1 of their licence (network management) and review the delivery of those steps within the timescales set out in the order. ORR confirmed in October 2012 that Network Rail has met the terms of the January 2012 freight performance order.

High level output specification:- A key feature of an access charges review. Under Schedule 4 of the 2005 Railways Act, the Secretary of State for Transport (for England and Wales) and Scottish Ministers (for Scotland) are obliged to send to ORR a high level output specification (HLOS) and a statement of funds available (SoFA), to ensure the railway industry has clear and timely information about the strategic outputs that Governments want the railway to deliver for the public funds they are prepared to make available. ORR must then determine the outputs that Network Rail must deliver to achieve the HLOS, the cost of delivering them in the most efficient way, and the implications for the charges payable by train operators to Network Rail for using the railway network.

The Train Accident Precursor Indicator Model (the PIM) managed by the Rail Safety and Standards Board (RSSB), measures the risk, per million train miles, of a train accident - i.e. collision, derailment, fire or striking a road vehicle on a level crossing. The measure incorporates 82 precursor events in eight groups. Around 65% of the risk arises from events largely under the control or the responsibility of Network Rail, e.g. track geometry, infrastructure failures, environmental factors (flooding, land slips etc.) and level crossing misuse.
The PIM risk indicator was set to a reference value of 100 at the end of March 2002 and the PIM risk indicator provides a measure of the change in risk relative to this level. A reduction in the index is therefore beneficial, denoting a reduction in risk.
