Apologies if this is covered elsewhere. I have yet to see a SWT class 456 displaying any information on their front destination screens. Every one I have seen has been blank, and the class has been in service with SWT for many months (over year, perhaps?). How is this squared with the requirements under the Disability Discrimination Act (DDA) to display such information? I think I recall class 458s requiring alterations to increase the size of their displays under the DDA requirements, along with the 442s. What is the problem with 456s showing this information?
