When you go about your normal commute, if you’re an able-bodied individual, you might not have noticed the subtle features that are embedded into the design of London Underground.
Whether that be the flooring colours, the poles, the seating fabric (moquette), or even those little grooves near the Tube doors.
Here is a virtual tour of some of our design features on the Tube. With an interview from Product Design Manager: Paul Marchant, who discusses the role design plays in accessibility and our network. 🗣
Product Design Manager: Paul Marchant
‘For contrast, the requirements for Rail, primary and contrast between the grab poles and the seating and then there’s also a requirement for flooring so there’s a contrast requirement for the flooring to be different in the vestibule, in other words, the part of the train with the doors, where you enter the train, and also the aisle as well.
So that has to be what we call a 30-point-contrast, but contrast isn’t necessarily a linear thing. You get different scores at different levels along the line that is contrast.
So those are the requirements. But we also try to do is also achieve good practice. We try and make contrast between all surfaces, so the side walls are one colour, the roof is another, the ceiling is another, what they call the pedestal area around the seating, the draft screens and stuff like that, and I think against all those contrasting elements if you’re not careful you’ll end up having is just almost something which is chequered.
So our job is actually to use colour within those contrast to orchestrate an interior that’s attractive, engaging and consistent, as far as our brand identity is concerned and also our customers’ expectations.’

A darker and lighter colour is used in different areas, which are the aisle (near the seats) and the area near the Tube doors.
This is so that passengers with reduced vision can denote the difference more easily.
The bottom two flooring samples are two options for lighter colours.

Priority and standard moquette
A slightly different coloured seating fabric is used on the standard and priority seats (the seats
closer to the doors).
This is to subtly denote the fact that these should be offered up to those who are less able to stand on their journey.
This is because they’re closer to the exits, so that passengers with reduced mobility can exit with comparative ease, as opposed to the seats in the
middle of the row.
An embedded badge with text which is weaved into the fabric also labels these seats.

These flooring grooves serve a few purposes.
- They are anti-slip in wet weather, where
the water sinks into the grooves and runs down the sides and off the train, preventing accidents.
- Another feature of these groves is that they provide tactile feedback for visually impaired
passengers who use a cane, so that they can get a feeling of where the door is in relation to
where they are standing, much like the ‘tactile paving’ we see on road crossings, with the raised
