Beginning in the 19th century, Jatinegara became one of Batavia's key transportation nodes. A horse tram was established in 1869 connecting Meester Cornelis to "Kota Intan" (the "Diamond City", the oldest Dutch settlement in Jakarta), via Harmoni. On January 31, 1873, the Dutch East Indian Railway Company established a railway line from Meester Cornelis to Buitenzorg (now Bogor). This line converged on the Meester Cornelis Station (now Jatinegara Station), one of the four oldest railway stations in Jakarta. On April 6, 1875, a railway connection between Meester Cornelis and Batavia was inaugurated, thus connecting the old city of Batavia with Buitenzorg. In the 1880s, the Batavian Eastern Railway Company (BOS) also constructed a 35-mile (56 km) route linking Batavia with Karawang via Meester Cornelis and Bekasi.
