§ Dr. Cable
To ask the Secretary of State for Transport, Local Government and the Regions what recent crowd safety assessments have taken place at the London railway stations that have had electronic ticket barriers installed(a) before and (b) since the barriers were installed; and if he will make a statement. 
§ Mr. Jamieson
I understand that prior to barriers being installed, a full risk assessment must be submitted to the HSE and the station operator who is installing the gates must carry out an operational safety assessment. Operation of the gates is assessed as part of the operational safety cases during field inspection. The gates must operate in such a way that they will be powered down, ie set to open, if unattended. There are now many562W gates in operation and I understand that there have been no significant safety concerns as a consequence of their use.
