I posted a similar shot of Cibatu PNKA shed staff posing on the running plate of Mallet 2-6-6-0 CC5001 some years ago. I believe this chap was the shed master.
Built in 1928 by Werkspoor near Amsterdam this locomotive has been preserved at Taman Mini in Jakarta.
Other Mallets dumped and in service were also on shed. I was invited to sign the visitor's book by the shed foreman. The last person to sign it before me was an English railway enthusiast who had visited in August 1979. One of these impressive Dutch built locomotives is also preserved in the Dutch National Railway Museum in Utrecht.
We were staying in the Mobil guesthouse in Puncak & rented a car & driver to reach Cibatu - a long ride on busy small roads.
