ELNA 2
German Reichsbahn class 9162
Germany 1925 37 produced
In the twenties, the ELNA (Engerer Lokomotiv-Normen-Ausschuß - Special locomotive standards committee) designed a range of standard locomotives to be built for private and light railways. The ELNA 2 was a 2-6-0T tank locomotive for light line service. Between 1925 and 1943, a total of 37 have been built. Among these were four built by Krauss, these differed in some aspects from the standard type.
The biggest customer was the Liegnitz-Rawitsch Railway with five locomotives. The ELNA 2 did not get a class number from the old Reichsbahn, but the East German Reichsbahn received 16 in 1949 and numbered them class 9162. One ELNA 2 that is still existing today is No. 146 of the Butzbach-Lich Railway.
