Koeltrog 1920 - 1922

This anonymous photograph, titled "Koeltrog", captures a large, cylindrical tank car on railway tracks in Surabaya, Indonesia, circa 1920-1922. The inscription on the side of the tank car reads "Zending Braat Soerabaia", indicating its likely use in transporting goods or materials for a religious organization. This photograph, now housed in the Rijksmuseum, offers a glimpse into the industrial landscape and transportation infrastructure of early 20th century Indonesia.
