Data from A E Durrant, Locomotives of Eastern Europe (New York: Augustus M Kelley, Publishers, 1966), pp 58, 60. and class info from [], edited by Nick Sharounis and John Zartaloodes. Works numbers were 565-573 in 1883 and 698-700 in 1887.
The layout of this radial tank was about as logical as could be expected. The three driving axles all lay under the boiler and ahead of the firebox. Long bearer beams embraced the sloping firebox and held the trailing axle under the footplate.
A photograph suggests that the firebox may have been a flat-topped Belpaire design. Ahead of it sat safety valves inside a brass casing and over the trailing axle, brass-cased steam dome over the center driving axle and a drum-shaped sand box over the leading axle.
Two touches redolent of North American practice were the tapered, broad-mouthed, spark arresting stack and the "cow-catcher" style pilot.l
