| Infrastructure managers use different types of detectors to monitor for unwanted or dangerous situations related to the interlocking operation. The outputs of such detectors are fed into the {{doc|IL|signalBox}} (interlocking) or the {{doc|IL|controller}} to react accordingly. Dependent on the purpose there can be the following base types classified:
| |
| *{{enum|avalanche}} – The detector detects avalanches, which may endanger the railway traffic.
| |
| *{{enum|cranks}} – The detector detects the presence of cranks for switch actuators at their normal location, e.g. in a special cabinet at the stationmaster.
| |
| *{{enum|derailment}} – The detector detects any derailed railway vehicle. It is often used in rear of tunnels or bridges to reduce the damages by derailed vehicles.
| |
| *{{enum|doors}} – The detector monitors the entry doors of equipment rooms.
| |
| *{{enum|fire}} – The detector detects fire or smoke in equipment cabinets or rooms.
| |
| *{{enum|flatWheel}} – The detector detects any flat wheel of a railway vehicle.
| |
| *{{enum|gas}} – The detector detects the excessive concentration of a particular gas in the vicinity.
| |
| *{{enum|hotWheelBox}} – The detector detects any hot axle box of railway vehicles.
| |
| *{{enum|intrusion}} – The detector monitors the access doors to any equipment cabinet or room in order to detect unauthorised access.
| |
| *{{enum|landSlide}} – The detector detects landslides or rockfalls, which may endanger the railway traffic.
| |
| *{{enum|loadingGauge}} – The detector detects any railway vehicle exceeding the loading gauge due to replaced goods or similar.
| |
| *{{enum|weighing}} – The detector checks the axle load of any railway vehicle against a pre-set limit.
| |
|
| |
| *{{enum|other:…}} – The detector is of another type. This is the optional extension of the list. Each entry needs to start with the string “other:” and shall have at least two letters in addition.
