The only suggested candidate for PKP
class Tp16 is KkStB class
175. One of two surviving examples, ČSD
414.404 (ex 175.04, StEG
2416/1894) was photographed at the Jaromeř depot on August 25, 2004.

The
very existence of this class with PKP is uncertain and has been
deduced from indirect information. According to some sources, in early 1920s PKP
had four engines with certain technical characteristics (weight and some
boiler details) corresponding to that of KkStB
class 175. It is, however, almost certain that this class designation, even
if envisaged for these locomotives, had in fact never been assigned. Class
175 was a development of earlier and not entirely successful class 75, built
for StEG railways in 1890 (initially
designated class Vn, later 43, re-classed in
October 1909 after StEG had been
incorporated into KkStB). Only six 75s were
built: all were later taken over by ČSD (class 414.3) and used mainly
for switching and with service trains. In 1894 StEG
introduced improved class Vg (later 44), which differed mainly in redesigned
boiler. Inordinately large grate (intended to burn low-grade coal) was
reduced in area from 4.35 to 3.24 sq.m and total
heating surface was increased from 166.1 to 181.5 sq.m,
due to longer drum. Number of flues remained unchanged, at 236. Boiler
pressure was increased from 10 to 12 bar. All this resulted in overall
improvement of boiler performance and tractive effort while maintaining the
ability to burn poor coals, but maximum speed remained unchanged, at 35 km/h.
This was too small a progress to warrant large-scale production and, although
production continued at StEG until 1900,
only nineteen examples were built in three small batches differing in minor
details. In 1909 they were re-classed 175 by KkStB. Just
like their predecessors, all 175s went to ČSD (class 414.4) and no
mention of their episode with Polish railways has been found in competent
Czech or Austrian sources. It seems possible that a few served very briefly
with PKP immediately after the war and were later handed over to ČSD
on the basis of international agreements, but – as mentioned above – this is
just a conjecture (such suggestion has been put forward in LP) which
still needs support. During WWII all engines of this type served with Českomoravské Protektorátni
Dráhy and thus were not given DRG
numbers; last of them, 414.408 (ex 175.08, StEG
2532/1896) was withdrawn in February 1968. Given
their low number and inconspicuous service, it is somehow surprising that two
engines of this type have survived until today, both in Czech Republic.
414.404 (ex 175.04, StEG 2416/1894) is a
property of the National Technical Museum, Prague, and can be seen at the Jaroměř depot; it had been one of the last engines of
this type in service. 414.407 (ex 175.07, StEG
2531/1896) has been preserved at the Chomutov depot
and is intended for a static display. Main technical data
