Thank you for your email of 6 April 2017.
I am sorry that the Design Guidance Documents/Standards for the Elizabeth Line have not been published online as we anticipated.
The delay is due to the change in brand - these will be updated over the next few weeks and we will publish them as soon as possible afterwards.
If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.
Yours sincerely
Graham Hurt FOI Case Officer
