The objective of this Standard is to provide RIMS with the requirements and recommendations for design (including functional and non-functional characteristics), procurement, and implementation of application based work on track authority systems (ABWTAS).
This Standard also provides vendors with a set of minimum requirements and functionality that would be reasonably expected of an ABWTAS.

This Standard applies to all rail transport operators, including light rail operators, who intend to procure and use an application based work on track authority system (ABWTAS).

The scope includes:
(a) system safety risk management;
(b) system requirements;
(c) system integration;
(d) change management;
(e) test and commissioning;
(f) maintenance;
(g) reliability, availability, maintainability, and safety of an ABWTAS.
