Like most Underground lines, the Piccadilly line is operated by a single type of rolling stock, in this case the 1973 tube stock, in the standard London Underground livery of blue, white and red.
Som stort set alle Underground-linjer er Piccadilly line betjent af en enkelt type rullende materiel, i dette tilfælde 1973-materiellet, i det sædvanlige London Underground-design i blå, hvid og rød.
