Sasaksaat railway tunnel is an railway tunnel that built by the Staatsspoorwegen (SS) between 1902 and 1903. The railway tunnel with the building wisdom number (BH) 503 is located on the route between Jakarta and Bandung at km 143+144 between Sasaksaat and Maswati Station, cutting through the Cidepong hills in Sasaksaat Village, Cipatat, West Bandung Regency, West Java.
Before the opening of the KCJB high-speed train line where one of the tunnels reaches the length of around 4.4 km (HSR Tunnel 6) on 2 October 2023, this tunnel was the longest active railway tunnel in Indonesia. 2nd longest after the inactive since 1980s Wilhelmina railway tunnel. In the tunnel with a length of 949 m[1] there are 35 sleko consisting of 17 left and 18 right from the direction of the Sasaksaat Station.[2]
The tunnel located in Operation Area II Bandung is a train tunnel with heavy traffic. The curved track when entering the tunnel from both the Sasaksaat Station and Maswati Station directions, the rails are given forced rails (gongsol). The large number of trains passing through requires special security in the tunnel so that at both ends of the tunnel there are guard posts for PJTW (tunnel guard officers).[3] The architecture of this tunnel is similar at first glance to the Mrawan railway tunnel in Sidomulyo, Silo, Jember.
