T3C

Side drawing of the T3C; source: PNPP.

Three light two-axle tank locomotives, built by Fablok in 1928 (factory types T1C and T2C), were followed by slightly larger, heavier and more powerful type T3C. Like its predecessor, it ran on saturated steam and featured Heusinger valve gear, but was fitted with piston valves instead of slide ones. Prototype (320/1930) was sold to Bankowa steelworks of Dąbrowa Górnicza, but proved too weak and was found to be of little use. Possibly it was sold to some other industrial establishment, but no information is available and its ultimate fate remains unknown.

According to PNPP, 320/1930 was the sole example of this type built. However, Fablok factory list (see References) and www.parowozy.net list one more example of this type, namely 667/1937, built for Solvay chemical plant of Kraków. Details are unknown. Be it as it was, no locomotive of this type has survived until today.

On the basis of T3C, a small two-axle tank locomotive for industry was developed after WWII. This locomotive, type 1B (commonly known as ‘Baziel’), remained in production from 1947 to 1959, in standard-gauge and narrow-gauge versions, both for domestic industrial establishments and for export. Type 1B is described under a separate entry.
