Signaling

Signalling equipment is a set of facilities that function to provide cues of shape, color or lighting placed at a certain place and gives a signal with a certain sense to regulate and control the trains operation.

Signal word comes from Latin "signum" meaning sign. The signal is the bearer of news about the railroad situation for the train crew. Viewed from its shape, the signal distinguished between optical signals and acoustic signals. Optical signals in the form of hand movement, a combination of arm position on the signal and light poles showned. Acoustic signals in the form of loudspeakers, flute, horn or whistle and others.

Types of Signalling equipment that have been used in Indonesia :

Icon Signalling Description Location
sinyal_alkmaar_icon Alkmaar Alkmaar Signalling moved by the signal handle mechanically / manually by human power. Signal handles with the signal bars on the signal poles are connected by wire or chain. Characteristics station using Alkmaar signal are all the switch manually using a switch  handle near by or in other words, Switchs not operated centrally. Alkmaar signaling system can not be assembled with the signal blocks, so can not be used at stations with other stations that use electrical signaling equipment. Ambarawa, Solo Kota, Wonogiri, Kalimas
sinyal_mekanik_icon manual Simenes & Halske Manual Siemens & Halske Signalling is a signaling system which is driven mechanically / manually by human power. Signal bars on the signal pole driven by signal handle that placed at the station. The signal handle with the signal bars on the signal pole are connected by wire or chain. The Alkmaar and manual Siemens & Halske Signalling used in the railway line with not high train travel frequency. Because interlocking signal not allow installed on both of them, accordingly the train travel security system was only based on news exchanges between stations, which are recorded in the book train news. Indro, Benteng, Kalibaru, Banyuwangi Baru
sinyal_mekanik_blok_icon semi-automatic Siemens & Halske Semi automatic Siemens & Halske Signalling system is driven with electro-mechanical device blocks mechanically/ manually. Physical form of this signaling is the same as manual Siemens & Halske Signalling that is placed an additional block cabinet. Role of the block cabinet as interlocking between stations. Characteristics of this signaling system is above the signal handles, there are a rotator and block cabinet with a few small glass window that could show a red or white color, and suppressor knobs on that small window. Semi-automatic Siemens & Halske Signalling can be used for main lines where the frequency of trains travel is high. Solo Jebres, Cepu, Bojonegoro, Surabaya Pasar Turi
