ČSD Class 477.0 is the last type of steam locomotive made by ČKD for Czechoslovak State Railways. In total 60 tank locomotives with axle arrangement 2′D′ 2′ (4-8-4) were produced in 1951-1952 and 1955.1 It was a tank locomotive development of the ČSD Class 475.0 locomotive.
This locomotive has 3 pistons (two on the sides and one in the middle) with an approximate power of 1590 kW
The first series (machines with serial numbers 001-006 and 008-036) had poor weight distribution on the tender and they had to be modified. The second series (machines with serial numbers 39-60) no longer had this defect and had more water in the tank on the sides.
Three are preserved, as of 2025 two of them were still operational (013 and 043).345
