This Network Rail standard applies to temporary and permanent Network Rail owned or managed, Shared or Outside Party Bridges as follows:

• all Underline Bridges spanning roads or under which vehicular traffic may reasonably be expected to pass;

• all Underline Bridges spanning navigable waterways, except those navigable only by small pleasure craft;

• all Overline Bridges carrying roads or which may reasonably be expected to carry vehicular traffic.

This Network Rail standard does not apply to:

• Bridge Strikes by small pleasure craft and other small vessels, which are unlikely to cause damage to Bridges;

• the management of the risk of Bridge Strikes by rail vehicles or their loads or by rail-mounted plant;

• the management of the risk of vehicle incursions onto Network Rail infrastructure, except where such incursions are the consequence of collisions of vehicles with parapets of a Bridges;

• operational requirements for the management of Bridge Strikes, including Late Reported Bridge Strikes, which are specified in NR/L3/OCS/043/7.4 National Control Instructions and Approved Code of Practice: Bridge Strikes from Road Vehicles and Waterborne Vessels.

This Network Rail standard applies to those appointed by or on behalf of Network Rail for the management of Overline and Underline Bridges, and for the examination and reporting of Bridge Strikes.

Guidance for Bridge Strike Nominees (BSN) on the management of Bridge Strikes is provided in:

• NR/GN/CIV/201 Managing Bridge Strike incidents - good practice guide for Bridge Strike Nominees.

Guidance on the management of the risk of Bridge Strikes is provided in:

• NR/GN/CIV/202 Management of the risk of Bridge Strikes.

Purpose

The purpose of this Network Rail standard is to:

• define the requirements for the management of Underline and Overline Bridges on Network Rail's infrastructure such that there is no unacceptable risk to safety as a result of Bridge Strikes;

• reduce the risks to the operational railway from Bridge Strikes, as far as is reasonably practicable, by assessing the safety risks at each Bridge and implementing mitigating measures as necessary;

• reduce train delays resulting from Bridge Strikes, as far as is reasonably practicable, without compromising the safety of train operations.
