FS Class 910

The Class 910 was a class of 2-6-2 tank locomotives designed by Guglielmo Cappa for the Rete Sicula, where they ran as Class 400 until the Italian State Railways absorbed them in 1905. They were meant for steep lines such as Messina to Palermo and also for local and commuter work, and the 2-6-2 layout let them run equally fast in both directions and avoid turntables at terminals. The first 19 were built by Ansaldo of Sampierdarena and the remaining 35 by Breda of Milan. They used saturated steam with compound expansion and outside Walschaerts valve gear. Most ended up working suburban trains around Milan. In 1929 one was converted experimentally to a Diesel-Zarlatti engine, and seven stayed in Yugoslavia after the Second World War. One is preserved at Pietrarsa.
