Data from PLM Wiki at [], last accessed 4 November 2011. See also DeGolyer, Volume 57, pp. 285+. Works numbers were 50289, 50340, 50387, 50429 in October 1918; 50433, 50505, 50521, 50525, 50530, 50640, 50648, 50665, 50698, 50702, 50705 in November.
These were duplicates of a small Consolidation design originally produced for the British railways in France, but also sold to Poland and other countries whose railways were affected by military action or by the break up of old railroad systems following World War One.
Piston valves measured 10" (254 mm ) in diameter.
NB: Heating surfaces in Locobase's specification use the external (water side) diameter. Using the internal (fire side), a frequent variation favored by several European railway systems, evaporative heating surface area came to 1,702 sq ft (158.15 sq m). Also, Locobase uses Baldwin's figure for the superheater. The PLM diagram gave the superheater area as 47.65 sq m (513 sq ft).
Data from A[nthony] E[dward] Durrant, Locomotives of Eastern Europe (New York: Augustus M Kelley, Publishers, 1966), pp 44-45, 49. but data from the First Romanian railway club ([] -- visited 14 January 2004--link no longer available). Baldwin's works numbers were 53342-53346, 53356-53360, 53367 in July 1920; 53390-53394, 53421-53425, 53456-53459 in July.
Following the supply of 15 surplus Pershing 2-8-0s in 1920 (Locobase 13382), the CFR ordered 50 more of a larger design by Alco and Baldwin. Cylinder volume increased by enlarging the diameter even though the stroke was reduced.
Baldwin's price was $65,000 each. Although delivered with the ability to burn either coal or oil, the class ran exclusively on oil (which Romania then had in abundance). They were rated at 1,600 tons up a 0.5% grade.
As with most 20th century US designs in Europe, the class quickly won over its crews with its reliability, durability, and power. The last of them -- 140.117 -- wasn't finally retired until 1976 and is preserved.

Saturated-steam engines supplied by Henschel (17 in 1909-works numbers 9335-9352) and SACM (Grafenstaden in Alsace Lorraine, 20 in 1913-works numbers 6464-6483).
See Locobase 1512 for the quartet of superheated updates delivered in the same year.

Exposition internationale des industries et du travail de Turin 1911 (Paris: Comite Francais des Expositions a l'Etranger, 1911), p. 18. See also A[nthony] E[dward] Durrant, Locomotives of Eastern Europe (New York: Augustus M Kelley, Publishers, 1966), pp 44-45, 49. Works numbers were 9353-9355 in 1910. 10310 in 1911.
Produced at the same time as the saturated Consolidations described in Locobase 1511, these locomotives tested several upgrades. Of this class Durrant commented: "Superheating seems to have been regarded with some suspicion by the Romanians, " as this design using superheat and piston valves, was not repeated.
