The class 564B 4-10-4 does not belong to RSR history, because all of these magnificent machines are still in service, albeit in rebuilt form, doing yeoman work on all the RSR's main routes. Their impeccable pedigree is apparent from both their contribution to the RSR's freight-moving business, which includes the Trans-Euro-Freight link, of which several routes pass over RSR metals, and their record of low operating costs and high reliability. To produce this superb machine, Ketterik built on the experience gained with the 364A pacific and 564A 4-10-0, combining the Doherty layout with a wide firebox. With their 8.3 square metres of grate area and 32.6 tons of tractive effort (not including the booster's 5.4 tons), these engines are the equal of every task. Haulage of loads of 1400 tons gross up the notorious Rovniebera bank at 100 kmh is an everyday achievement. The 564B turned out to be a first-class investment which gave excellent returns for many years.
