## Product Specification for an Obstacle Detection System at Level Crossings

active, Most Current
 Organization: NR Publication Date: 1 September 2018 Status: active Page Count: 52
##### scope:

This specification applies to an Obstacle Detection System intended to be used at MCB-OD level crossings and any similar crossing type that might be introduced later where assessed to be fit for purpose.

Purpose

This specification defines the requirements of an Obstacle Detection System for use at Manually Controlled Barriers with Obstacle Detection (MCB-OD) level crossings and any similar crossing type that might be introduced later. It allows the procurement of an Obstacle Detection System that can be used at level crossings, in particular MCB-OD with minimum changes and at other level crossings where reduction in risk or automation is required.

There are several methods of achieving the Obstacle Detection System. This specification has been written so it is technology agnostic.

NOTE See Appendix A for a detailed explanation about MCB-OD level crossings.

Words with leading capitals are defined terms used in the context of their definition in section 5.
