When I first visited the Innocenti factory site the new road in the previous shot was not yet finished; you can see the borders for it in the right hand shot taken during construction. Next to the Innse water tower was this old building with railway tracks running through it, obviously a loading shed for incoming parts and outgoing finished machines. There was a branch line running from the factory through Lambrate to the main line near Lambrate FS and you can still see some evidence of it today. Lambretta scooters were apparantly shipped to the UK by this method and parts for Innocenti cars (based on BMC models) were shipped back from the UK.  Not my photos, provinence is unknown to me.
