Fablok TKh49
class of Polish 0-6-0T locomotives

The Fablok T3A also known as TKh49 or Ferrum 47 / 724 is a class of Polish steam industrial tank locomotive. It was built by Fablok in 1948-1961 years.
History
The locomotive is based on a draft from the years 1927-1929; seven locomotives of the factory designation T1A, basing upon Austrian license, were built by Fablok then. Its development with a superheater was Fablok T2A (Ferrum 29 or Tkh29), of which eleven were built before World War II. The name Ferrum came from Ferrum Ironworks, for which it was developed. The technical documentation survived until after World War II and ten more T2A were manufactured. Due to big need of industrial locomotives in looted post-war Poland, it was decided to develop it into a simplified class of locomotive, factory name T3A or Ferrum 47, from 1947 year. Among other it lacked a superheater. At least 437 examples were made in the years 1948 - 1961, including 30 to China, 3 to Romania and 3 to Hungary. Some factory records indicate 480 locomotives made, but details are not confirmed. Later production locomotives, with more welding adopted, were referred to as Ferrum 724.

Why this record matters
The phrase “class of Polish 0-6-0T locomotives” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 21, 2025. The linked authority identifier is Q280117. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1948, 1961, 1927 and 1929.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
