TKh16

 

 

KkStB 464.02 ‘Auffenberg’ (Krauss Linz 6520/1911), operated by BLB; location and date unknown. According to some sources, this locomotive was taken over by PKP and designated TKh16-1. Source: TK vol. 3.

 

 

Yet another ‘class that never was’: TKh16. According to some sources, this designation was intended for a single kkStB class 464 tank locomotive. Whether it was actually assigned is a different story.

On July 1, 1889, Bukowinaer Lokalbahnen (BLB) in Eastern Galicia, which commenced operation in 1884, were taken over by Austro-Hungarian state railways kkStB, but retained some degree of autonomy. In 1909 it purchased a 0-3-0 tank locomotive for mixed traffic from Krauss Linz (6198/09), which was given the individual name ‘Pflaum’. Two more engines of the same type followed later: Krauss Linz 6520/1911 ‘Auffenberg’ and 6776/1913 (no individual name). These three locomotives were given kkStB service numbers 464.01 through 03. They featured inner frame and Allan valve gear and ran on superheated steam, which was rather uncommon with mixed traffic locomotives built for Austro-Hungarian local railways.

After the war 464.01 and 464.03 were taken over by Romanian Căile Ferate Române (CFR) and retained their original service numbers. They were withdrawn at the Paşcani depot in 1936 and 1937, respectively. The fate of the 464.02 is unclear. According to some sources (e.g. ITFR) it was taken by Austrian troops on their withdrawal from Ukraine and transferred to PKP in May 1919. Service designation TKh16-1 was supposedly intended for this engine. Other sources (e.g. TK) suggest that it possibly fell into Russian hands and its further fate is unknown. Class TKh16 is not mentioned in Charakterystyki parowozów (Steam Locomotive Characteristics) by A. Czeczott, issued by the Ministry of Transport in 1927. Thus, if this locomotive actually served with PKP, it is unclear why it was withdrawn after less than sixteen years in use. It seems that, until some hitherto unknown documents are revealed, this question shall remain open.
