These were originally built as 0-6-0s, but the success of the 0-4+4-0 supplied a few year earlier inspired a joining of several engines into twin-engine sets.. Wiener (1930) for data.
Data from Lionel Wiener, Articulated Locomotives (1930) and Wikipedia's "Mastodonte dei Giovi (locomotive)" entry at [], last accessed 19 August 2019.
So-called duplex or twin locomotives, this design consisted of two engines joined together at a pivot and operated by one crew. Stephenson supplied the 0-4-0 locomotives.
In service on a section of line that featured 3 1/2% grades, the "Mastodonte de Genovi" proved quite successful according to Wiener, a finding contrary to the Stephenson Company's expectations.
Still in service, all ten were taken into the Strade Ferrate d' Alta Italia (SFAI) in 1865.
Cockerill's slight variation on the twin locomotives design intended for 3 1/2% grades in the Italian mountains. Wiener (1930) for data.
