ALe 426/506 TAF (acronym of Treno ad Alta Frequentazione) is an Italian Electric Multiple Unit (EMU) used mainly on commuter regional trains. Concept design has been made by Italian designer Pininfarina.
Two different companies employ them: Trenitalia and Ferrovie Nord Milano (FNM). Some slightly modified version of the EMU have been purchased by Moroccan Railways in 2006.[1]
