This Order amends the Rail Vehicle Accessibility (Croydon Tramlink Class CR4000 Vehicles) Exemption Order 2001 (S.I. 2001/3952, amended by S.I 2002/3001) which authorises the use of specified rail vehicles operated on the Croydon Tramlink even though they do not comply with certain requirements of the Rail Vehicle Accessibility Regulations 1998 (S.I. 1998/2456, amended by S.I. 2000/3215). This Order extends the expiry date of the exemption granted because the vehicles do not have a structure or fitting to prevent a wheelchair moving or tipping. The Order imposes a condition that a certain number of the vehicles must be made compliant with this requirement by the end of October 2005, and extends the expiry date for the exemption to the end of 31 December 2005.
