TfL still uses UTS in modified form and hugely reduced quantities, as detailed in Wikipedia. Decoding vital info centrally on the right hand side, machine series starting 01 upwards related to now-closed staffed Ticket Office windows; 10 onwards relate to self-service Fewfare machines; series 31 etc comprise a complex Multifare variant.
This product is ideal for travelers who need a UTS London Underground ticket for the Piccadilly Line, requiring a trip to station Middlesex TW7 in the West End of London.
