Diagram 66: General Properties of a Train
If several engines are running as a multiple unit, then the horse power of each engine is
added to the total power of the multiple unit. Since the total power is higher than the individual
power of each particular engine the multiple unit is able to accelerate faster and
to run with a certain train tonnage at a higher maximum speed.
In the example displayed above, a train is arranged. Based on the total power of the assigned
engines the program calculates a maximum speed of ... miles per hour.
The time needed to accelerate or decelerate an engine or train is additionally scaled and
shortened using the scale factor of the Railroad Clock (see chapter 11, ” The Clock”). If
for example the scale factor of the clock is 10, then the calculated times are shortened to
the tenth part. Even this shortening, however, results in timing, which is often found too
slow. For this reason it is possible to adjust the inertia of each engine individually. In
this way it is possible to accelerate or decelerate an engine without inertia or with the
inertia of a real engine. Any setting between these extreme cases can be selected. It is
also possible to adjust the inertia for acceleration and deceleration separately (see
Diagram 58).
Do not be concerned if this sounds too complicated - especially in the beginning. For
each engine which is created TrainController assumes default settings for horse
power, train tonnage and momentum. You are not required to set it. The default values
result in a moderate behaviour for acceleration and deceleration which can be adjusted
