=== Agudio (1884) ===
The Agudio rack system<ref>{{Cite web |last=Gamboni |first=Antonio |title=L'antica Funicolare di Superga |url=http://www.clamfer.it/11_Funicolari/Funicolare%20Superga/Funicolare%20Superga.htm |access-date=2022-04-30}}</ref> was invented by Tommaso Agudio. Its only long-lived application was on the [[Sassi–Superga tramway]] which opened in 1884. It used a vertical rack with cog wheels on each side of the central rack. Its unique feature, however, was that the 'locomotive' was propelled by means of an endless cable driven from an engine house at the foot of the incline. It was converted to use the Strub rack system in 1934.<ref>{{cite web |title=Tranvia da Borgo Sassi a Superga   |url=https://www.histouring.com/en/historical-places/tranvia-da-borgo-sassi-a-superga/ |publisher=histouring}}</ref>
