For each direction the speed profile contains at most 15 entries for 15 virtual speed
steps of all in all 1000. Intermediate values are calculated accordingly. In this way it is
possible to calculate the scale speed for each of the 1000 virtual speed steps.
The entries of the speed profile are distributed equally in the range of the available
virtual speed steps. There is no coherence between the number of entries and the
number of speed steps of the decoder.
There are five procedures to perform the measurement:
Manual measurement of one single speed step (stop watch)
Automatic measurement of one single speed step by running the engine from one
momentary track contact to another
Automatic measurement of one single speed step by running the engine on a track section
with three occupancy sensors
Automatic measurement of the complete speed profile with momentary track contacts
Automatic measurement of the complete speed profile with three occupancy sensors
You can measure single values of the speed profile manually like using a stop watch.
However TrainController provides the possibility to measure all relevant values between
the threshold speed and the maximum speed automatically. For this purpose you
have to arrange a track section, which is either limited by a momentary track sensor on
each side, or which is monitored by track occupation sensors. To each track sensor a
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.
Finally an additional run into each direction is performed to determine the behaviour of
the engine when decelerated.
