Data from A E Durrant, Locomotives of Eastern Europe (New York: Augustus M Kelley, Publishers, 1966), pp 44, 49. Works numbers were 371-376, 397-402 in 1869 and 421-428 in 1870.
These were the passenger engines that, together with a larger batch of 55 0-4-2 goods locomotives, stocked the Romanian State Railways as they opened in 1870. Compared to earlier Singles, the class's boilers began service with boilers pressed to 120+ psi.
