Via Aemilia
The Milan–Bologna railway is the northern part of the traditional main north-south trunk line of the Italian railway network. It closely follows the ancient Roman Road, the Via Aemilia. The line was opened between 1859 and 1861 as a single-line railway, and was doubled between 1866 and 1894. It was electrified at 3,000 volts DC in 1938. High-speed trains on the route have used the parallel Milan–Bologna high-speed line since 13 December 2008.
