Type T1A, built in small numbers by Fablok on the
basis of documentation purchased from StEG in 1927, was soon developed into an improved and more
powerful superheated T2A. Similar in external appearance, new locomotive
featured copper firebox and piston valves, was slightly longer and lighter.
The sole example of this version (Fablok 408/1929) was purchased by Kolej Elektryczna Warszawa-Młociny-Modlin (Warszawa-Młociny-Modlin Electric Railway),
which already had one T1A in operation. Plans to electrify this railway in
fact failed to materialize, due to the world crisis, and the line was never
completed. Normal traffic was later
suspended and the line was used only by military authorities, providing a
connection to the military depots located near Palmiry.
Operation was entrusted to PKP and
the locomotive was numbered TKh29-1. In 1939 it fell into German hands and
was impressed into DRG as 89 1101.
Withdrawn in May 1944, it was transferred to RAW Linz, then taken over by Austrian state railways ÖBB and finally withdrawn in November
1946. Second
version of this type appeared almost in parallel with the first one and
featured modified boiler, again with steel firebox. It was slightly longer
and had lower smokestack. It was commonly known as ‘Ferrum
29’. Data concerning production of this variant vary considerably, depending
on source. PNPP gives ten examples
built between 1929 and 1941, but only four of these are confirmed by the Fablok factory
list (see References). Given the fact that two engines listed in PNPP as T1As were in fact most
probably T2As, total pre-war production was six examples; this is consistent
with AP, which gives combined
production of T1A and T2A as twelve engines. According to PNPP, further ten examples were built
between 1946 and 1948. Nine of these are confirmed by the Fablok factory list, but these
locomotives were most probably T3As (also known as ‘Ferrum
47’, described under a separate entry), which had been developed from T2A,
but ran on saturated steam. During overhauls, T2As were fitted with electric
lighting; in some examples, vacuum brakes were replaced by air units. These
locomotives remained in service with various industrial establishments until
late 1970s; not a single example has been preserved. Main technical data –
