The Rail Vehicle Accessibility (Anglia Railways Class 170/2 Vehicles) Exemption Order 1999
This Order authorises the use of specified rail vehicles forming Class 170/2 diesel multiple-units, although they do not conform with certain requirements of the Rail Vehicle Accessibility Regulations 1998 because warning sounds are emitted whenever the passenger doors in the sides of the vehicles are closed and passenger operation of some doors is by means of beam operated door sensors. It sets time limits on the authorisations and imposes conditions.
