This is certainly a not very typical situation for a
S1! As far as I know, this picture was
taken in or near Katowice (or rather Kattowitz),
probably before WWI. Any idea?

First
Prussian express locomotives with compound engines featured the 1-2-0 axle
arrangement and were designed by August von Borries. Only fourteen examples
were delivered, including eight by Hanomag (between 1884 and 1885) and
six by Henschel (in 1887); all were assigned to the Hannover regional
depot. In 1884 a single-expansion variant appeared, which featured modified
boiler and slightly larger drivers. Due to simplicity of manufacture and
maintenance it found more favor with Prussian railway authorities, was
standardized (Musterblatt III-2)
and 260 examples were delivered until the termination of production in 1898.
After 1903 both these types were classed S1 by KPEV, the compound and
single-expansion versions being referred to as Bauart Hannover and Bauart Magdeburg,
respectively. Both were coupled with three-axle 3T12 tenders. Class S1 also
included a few (possibly three) locomotives with the same axle
arrangement, from a batch of thirty
originally built for the Cöln-Mindener Eisenbahn that had survived in
service until the introduction of the new designation system. Class
S1 was a successful engine for its time, but soon became surpassed by more
modern designs offering higher speed and better running qualities (due to
two-axle pony truck). Following the appearance of more powerful engines,
class S1 was relegated to passenger traffic. Last compounds survived in
service until 1922, but the majority had been withdrawn before WWI. Singles
fared slightly better: four were even provisionally assigned DRG
service numbers 12 7001 through 7004, but these were in fact never given, as last
engines of this type were withdrawn in 1923. After
WWI Polish railways obtained fourteen locomotives of this type, all of the
single-expansion variety, built between 1890 and 1895. These comparatively
light and weak engines were used for a short time with secondary passenger
trains. Within the framework of the new designation system they were classed
Pc1, but it is not sure if all in fact underwent renumbering, as the official
1927 Ministry of Transport type list does not include this class in service.
Some sources state that last three survived until 1931, which most probably
is incorrect. Not a single S1 has been preserved. Main technical data*
*) All data refer to the single-expansion version. References
