Light Reflective Values of Jubilee Line in-car Grab Handles

You asked

I would be interested to know what the exact LRV values are of the upright and horizontal grab handles, and the panels to which they are fixed, within the passenger cars are? I understand that these grey handles comply with RVAR 2010, having been changed from yellow to grey. It always seemed to me that yellow was ideal for people with limited sight and that they new grey does not contrast sufficiently well with the cream panels. I would like to know - what are the exact colour type names and what the light reflective values of both colours are? Many thanks,

Our ref: FOI-1187-1920/GH

Thank you for your request received by Transport for London (TfL) on 24 July 2019 asking for information about Jubilee line grab handles.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. I can confirm that we do hold the information you require.

The attached slide shows the Jubilee line interior colour scheme pre- and post-refurbishment as measured against the requirement of the Rail Vehicle Accessibility Regulations (RVAR) 2010. This is defined in the RVAR Guidance Notes (2002) as having contrast “…in static conditions, a difference of 30% or more is considered in these values to be adequate” utilising Light Reflectance Value (LRV).

The colour contrast level meets the minimum requirement in all areas of the train for critical surfaces to contrast with the adjacent areas. As an example, the colour scheme is designed with the grab poles and interior trim having 45 points contrast. The trains also now feature improved contrasting flooring between the door vestibules and seating areas to help those with visual impairments navigate inside the train, areas for wheelchair users and improved lighting to create a more comfortable environment for all customers.

If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.  

Yours sincerely
