A locomotive with wagons drives from the right into a terminal station. Two cases are considered in this documentation:
1) the locomotive is at the front of the train (i.e. the train moves forward into the terminal station with the locomotive ahead);
2) The locomotive is at the rear of the train (i.e. the train goes backwards to the terminal station with the wagons ahead).
In both cases it is assumed that only the locomotive can trigger a sensor (the wagons should not be able to trigger sensors).
Under these conditions, how can the train be stoped in time?

Rocrail offers the possibility to use a sensor for the event "SHORTIN" in addition to the events for "enter" and "in". This "shortin" sensor takes over the function of the "in" sensor, if this has been configured accordingly in the properties of the locomotive:
- Locomotive / Properties / Details / "Use Shortin" = YES
The "shortin" sensor is placed directly behind the "enter" sensor.

If the locomotive drives to the terminal station in front of the train, the "SHORTIN" sensor has no meaning. The locomotive travels to the "IN" sensor and stops there.
- Locomotive / Properties / Details / "Use shortin event" = NO (default)

If the locomotive pushes the train into the station, the "SHORTIN" sensor takes over the "IN" event if the locomotive has been configured accordingly!
- Locomotive / Properties / Details / "Use shortin event" = YES !!!

The block identifier is "bk02".
The block "bk02" has feedback sensors for the events ENTER, IN and SHORTIN.
The block "bk02" should always be longer than the longest train (locomotive with wagons) that occupies this block.

The sensors are called "fb02+", "fb02-" and "fb02s".
"fb02+" on the plus side of the block;
"fb02-" on the minus side of the block.
"fb02s" on the minus side of the block (between "fb02+" and "fb02-").

In this example, the sensors are to be implemented as current sensors. Only the locomotive triggers these sensors!
The length of a sensor should be as long as the locomotive needs to come to a complete stop within the sensor (i.e. does not drive beyond the sensor ! ).

Für die Richtung dieses Beispiels ist die Minus-Seite des Blocks die "Enter"-Seite des Blocks; also
- Rückmelder "fb02-" ist für das "enter" Ereignis verantwortlich und
- Rückmelder "fb02+" ist für das "in" Ereignis verantwortlich.
- Rückmelder "fb02s" ist für das "shortin" Ereignis verantwortlich.

Die Lokomotiven müssen noch geeignet konfiguriert werden.

Die Lok "lc_b1" ist vorne am Zug.
Die Lok "lc_b2" ist hinten am Zug.
