After World War I, says Romania's Alto Travel Agency website ([], visited 9 December 2002), the CFR standardized on the Prussian KPEV's P8 Ten-wheeler as its "utility passenger" class. After several German builders delivered 131 locomotives, Romanian builders produced their first 130 in 1932 at the Resita shops. Resita contributed 138 more while Budapest's Malaxa Works added 91 engines.
Data from "4-6-0 Compound Locomotives, Roumanian [sic] State Rys", Locomotive Magazine, Volume XXII [22] (14 October 1916], pp. 196-197. For a description and illustration of the Z- or oblique crank axle, see "Oblique Type Crank Axles", The Engineer, Volume 97, No (15 April 1904), p. 394.
NB: Try as he might, Locobase hasn't been able to locate much data or history on this class.
These de Glehn compounds were the only compounds to be built specifically for the Romanian railways. The power layout put the two low-pressure cylinders outside and driving on the second axle. The two high-pressure cylinders were nestled under the smokebox and turned a "Z" (or oblique) crank that formed the leading axle. Unlike other de Glehn locomotives, the provision of separate valve gear for HP and LP cylinders did not include the ability to set their cutoffs independently, which meant that the efficiency was not "so perfect theoretically", said the Locomotive report. But it also meant the mechanism was "less subject to abuse, when handled by an unskilful driver, than the De Glehn arrangement."
Engineer's report on the axle shows the earlier Martin drive design for such axles, which derived its crank action from connecting the right side crank pin to an offset mounting on the driver. The cast Z crank used in these Ten-wheelers put the cranks near the middle of the axle, between two axle stubs exending inward from the drivers. One set of eccentrics were bolted to the crank that lay on the axle line and the other set was offset.
