The only TKy photo known to me is that of TKy 203, taken by Tadeusz Suchorolski
on June 26, 1970, in Warsaw; the engine is obviously in a poor condition.

The
1-5-0 axle arrangement was very popular in Europe with heavy freight locomotives.
However, probably the only European tank Decapods
were three heavy freighters, built in 1913 for an Upper Silesian company with
a somewhat lengthy name of Sandbahn-Gesellschaft
der Gräflich von Ballestrem’schen
und A. Borsig’schen Steinkohlenwerke.
This company was a division of a large enterprise, owned jointly by the Ballestrem family and Borsig locomotive works, which
operated several collieries and had to provide transportation of filling
materials from sand pits. For this purpose, powerful locomotives were needed;
ability to run on tracks of not necessarily good quality, with steep
gradients and tight curves, was mandatory. These
locomotives, built – not unexpectedly – by Borsig were numbered 1
(8395/1913), 2 (8396/1913) and 3 (8397/1913); No.2 was given an individual
name ‘Adolf Märklin’. They were powerful for their
time, but axle load of 17 tonnes was high by
current standards. Despite being operated on rather short lines between sand
pits and collieries, they had to be coaled frequently, due to modest coal-box
capacity of just 3 tonnes and high consumption. All
three examples remained in use until 1945 and after the war were taken over
by Polish authorities. Due to their axle arrangement they were classed TKy. No.1 became TKy 203; it
was operated by Kotlarnia
sand pit and later transferred to the Siekierki power plant in Warsaw, where it survived until
1971. No.2, re-numbered TKy 201, was initially
taken over by the Jastrzębie
colliery and later by ZTKiGK Boguszowice
filling materials enterprise. No.3 became TKy 202
and initially went to Kotlarnia;
later it was taken over by the Miechowice colliery.
Withdrawal dated of the last two engines are not known, but none has been
preserved. In some sources numerical designations are given with dash, e.g.
TKy-201. 1-5-0
tank locomotives from Borsig
were further developed into even more powerful 1-5-1s, built for the Halberstadt-Blankenburger Eisenbahn
and known as Tierklasse.
These, in turn, served as a basis for KPEV
class T20 (later DRG class 95) and
several locomotives built for Silesian sand railways. The latter served in
Poland after 1945 as class TKz and are described
under a separate entry. Main technical data
