Train crew signal
A train staff signal is an optical or acoustic signal for communication between the staff of a train or between the staff of several trains.
Signals in Germany
In the Deutsche Bahn signal book , train crew signals are designated as Zp1 to Zp12 . The following signals currently exist:
- Zp 1 "attention signal "
- This acoustic signal is given by a moderately long whistle from the motor vehicle or another acoustic signal generator (z. B. Typhon) and serves as a warning z. B. at construction sites, unrestricted level crossings or blind spots in front of the approach of a train. In addition, this signal is used to confirm the reception of another signal and is used at train stations to announce the imminent departure. There is no optical equivalent to this signal.
- Zp 2 " Apply handbrake moderately"
- This acoustic signal, consisting of a short whistle , prompts you to apply the hand brakes moderately.
- Zp 3 " Apply hand brakes strongly"
- This acoustic signal, given by three short whistles in succession, prompts you to apply the hand brakes hard.
- Zp 4 "Release hand brakes"
- This acoustic signal, in the form of two moderately long tones, prompts you to release the hand brakes.
- Zp 5 "emergency signal"
- Something extraordinary has happened to the train. Braking and helping. This acoustic signal, given by groups of three short tones in succession, prompts the train to stop immediately. The signal tone is identical to that of the signal Sh 5 . In certain cases it can also be used to secure danger spots by placing three blast capsules at short intervals; in this case the train triggers this signal itself when rolling over it.
- Zp 6 to Zp 8 " brake test "
- These signals are given by hand or by a stationary brake test system, which consists of three white lamps placed one above the other.
- Zp 6 means “ apply the brake ” and is signaled by a white light or by bringing the outstretched arms together over the head.
- Zp 7 means "release the brake" and is signaled by two white lights one above the other or by lowering the outstretched arms next to the body.
- Zp 8 means “brake ok” and is signaled by three white lights arranged one above the other or by holding up both arms.
- Zp 9 " Depart "
- This signal, symbolized by an illuminated green circle or by holding up a white command stick with a green border, prompts the driver to leave.
- Zp 10 "close doors"
- This signal is given (in the area of the former Deutsche Reichsbahn ) either by telephone or by means of an illuminated white stripe lying on the floor and asks the driver to close the doors. In the area of S-Bahn trains , this signal can also be given by a white “T”.
- Zp 11 "Coming"
- This signal can be given optically or acoustically. The optical signal consists of a long-short-long lighting up of a lamp and is used on stationary signals. The acoustic signal consists of a long-short-long or low-high-low combination of three tones (the Morse code for "K"). The signal is given for calling a waiting train in the station or requested in a passenger over the public address system given to train drivers on to sit down with the driver in touch.
- Zp 12 "No boundary marks"
- The acoustic signal consists of a short-short-long-short combination of four tones (the Morse code for "F"). It means that the tip or the end of the train at a switch does not protrude beyond the boundary sign .
