Met S stock interior

There was something to do with DDA (now scrapped but bits put in the Equalities Act 2010) and having a uniform colour! I agree, they should have been Magenta!

We covered handrails in a different thread, and it's all to do with standing out against the ambient colour. I'm sure prjb can add to this again if I'm mistaken.

EDIT

He's beaten me to it!

Given the interiors, I would have thought that black especially would have contrasted well. The brown on the bakerloo doesn't do too badly.

;D

Ah yes, if only.... Brushed stainless steel was so robust and long lasting.
I was lucky enough to visit the Innotrans exhibition and see that the EC Disability regs are interpreted more flexibly in other EC countries' modern trains. There, brushed stainless steel handrails are still very common. Indeed in some cases they contrasted with surroundings well for me, but perhaps less so for someone with very low vision.
The RVAR defines contrast as “contrast” means contrast in the amount of light reflected;
The RVAR Guidance on handholds states "People who have low vision need to be able to identify the handrails against other surfaces within view in order to use them. Most people will find this easier when the handrail contrasts clearly with surrounding
surfaces."
Then when you recall that the suite of handholds includes a variety of surroundings ranging from near white panels to a general collection and variety of colour and texture when there are people in the car and floor to ceiling handrails, nothing that isn't a fairly bright colour is going to meet the spirit or letter of the not unreasonable requirement. Hence the Met line route colour really isn't going to be acceptable.
As you may have seen, bright yellow, pale to mid blue, vivid green are used in various LU stock and there are other bright shades in some modern RVAR regulated TOC fleets. I think LU design taste wouldn't go for peppermint etc though! Quite right in my opinion.

I think, Met line purple would stand out more than the yellow, the interiors are already quite yellow especially the lighting and the ceiling being quite a cream colour

With the new "S-Stock" - Initially the users can also enjoy the "New Car Smell" initially, just like the new Victoria Line and Docklands light railway trains!!

I presume the Disability Regulations are not only to cover those with poor eyesight but also the colour blind.

It does seem to me as though all lines should have stock to identical internal and external decoration and that selectable visual and audible cues should be used to differentiate which line a train is running on and which destination it is running to.
Why the need for expensive arty farty line identity as decoration except to placate designers ? As ever money, it seems, is no object.

At the end of the day I doubt that able bodied passengers are that fussy about decor, service and punctuality being far more important to the average commuter.
