contact indicator (see section 4, “Contact Indicators”) must be assigned. To measure
the speed profile the engine is run back and forth automatically by TrainController
The program starts the measurement with the threshold speed. Each time the engine has
passed the track section in both directions the engine is accelerated to measure the next
speed level. This is repeated until the engine reaches its maximum speed. Monitoring
the contact indicators TrainController is able to determine, when the engine enters
or leaves the track section used for this measurement.
Before an automatic measurement of the speed profile is performed, it is important
to adjust the threshold speed of the engine. If the threshold speed step is reduced
later, after measurement of the speed profile, then the measurement must
be repeated.
The different methods of performing an automatic measurement with momentary track
contacts or occupancy sensors are outlined in the following. Further details about the
different types of sensors and their usage can be found in section 5.8, “Arranging Indicators
and Markers in a Block”.
Measuring with Momentary Track Contacts
Diagram 76: Measurement with Momentary Track Contacts
For the measurement with momentary contacts two momentary contacts are needed.
These contacts are associated with two contact indicators, called “Start” and “End”. The
length of the track section used for the measurement is determined by the distance between
the two track contacts.
To start the measurement put the engine on the track a certain distance left of indicator
“Start” heading to indicator “Start”. The engine will be started in the forward direction.
When it reaches the indicator “Start” the measurement of the current speed step begins.
When the engine reaches the indicator “End”, then the engine is decelerated and
stopped. Now the engine reverses direction and the measurement of the same speed step
in the backward direction is performed, now using indicator “End” for the beginning of
