Moquette explained

Derived from the French word for carpet, moquette is a predominantly wool, woven-pile fabric in which cut or uncut threads form a short, dense, cut or loop pile. As well as giving it a velvet-like feel, the pile construction is exceptionally durable and ideally suited to hard-wearing applications, such as public transport.  Moquette is particularly famous for its use on London Transport tube trains and buses, although large numbers of regional bus companies also had their own bespoke designs. During the heyday of the railway, there were some ten moquette manufacturers, but after nationalisation in the 1960s, the number of customers plummeted and today only two suppliers remain. Vintage moquette is very hard to come by, and the London Transport Museum strictly controls the remaining stock of many iconic designs.
