This prototype was designed as a Mk2 Class 440 tailored for Commuter duties and would have been the very first unit of a large class which was to revamp Cercanias services. Persistent reliability concerns eventually led RENFE to reconsider its plans in the late-80s and to opt for Class 446s, instead.
