B2503 Locomotive (1984)

  • B2503s

Steam locomotives of the Ambarawa Railway Museum from PT. Kereta Api Indonesia (Persero) were numbered according to the Japanese system, with a letter to indicate the number of powered axles followed by two digits for the class (10-49 tank, 50 upwards tender locomotives), then the individual number. The locomotives at Ambarawa were brought here around 1977 at a time when steam was still in widespread use on the island of Java. Therefore, they were not always the best examples available.

    Ambarawa is like many towns in the highlands of Central Java that are cooler above the low lying north coast. It is known over time as the location of a historic railway and railway museum.
