Here's the second section of the report from Roger Davies covering his trip to Milan, showing more modern trams and examples of buses.
A long Sirio at the Castillo terminus
Single end of a Sirio circumnavigating the head office with the Castillo.
By contrast to the trams, the bus fleet is extremely modern, boasting many Eco buses including upwards of 100 Euro 6 powered Solaris types. Most are in a green livery, green bands having been added to some of the earlier orange painted ones.
