Definition of the train

The procedure to define a new Traffic loads (new train load)

Open service Load.
Expand branch Traffic loads.
Start function Single Traffic Loads.
The Load patterns manager is opened on the screen.
If no load pattern has been defined, the input dialogue is opened directly on the screen.
Otherwise, click button [New].
The Train load input dialogue is opened on the screen.
Input the load.
Confirm with [OK].

Train load input dialogue

Name	Specifies the name of the load pattern.
Description	Describes the load pattern.
Type	Specifies the type of the entity that will be added to the load pattern.
Add new entity	Adds a new entity into the load pattern.

List of defined entities with their parameters	Lists all the added entities and their parameters

Parameters of a point

Direction	Defines the direction of the force.
Force	Specifies the size of the load.
Position x1	Defines the x-coordinate of the point in which the load acts.
Position y1	Defines the y-coordinate of the point in which the load acts.
Repeats x	Specifies how many times the load entity is repeated along the x-axis.
Delta x	Specifies the distance between individual load entities in the x-direction.
Repeats y	Specifies how many times the load entity is repeated along the y-axis.
Delta y	Specifies the distance between individual load entities in the y-direction.

Parameters of a line

Direction	Defines the direction of the force.
Force	Specifies the size of the load.

Parameters of a rectangle

Direction	Defines the direction of the force.
Force	Specifies the size of the load.
Position x1	Defines the x-coordinate of the first corner of the rectangle over which the load acts.
Position y1	Defines the y-coordinate of the first corner of the rectangle over which the load acts.
Position x2	Defines the x-coordinate of the opposite corner of the rectangle over which the load acts.
Position y2	Defines the y-coordinate of the opposite corner of the rectangle over which the load acts.
Repeats x	Specifies how many times the load entity is repeated along the x-axis.
Delta x	Specifies the distance between individual load entities in the x-direction.
Repeats y	Specifies how many times the load entity is repeated along the y-axis.
Delta y	Specifies the distance between individual load entities in the y-direction.

Parameters of a turning point

The load pattern (train load) may be composed of a great number of individual "parts". For example, imagine a standard train with many carriages. If such a load pattern moves along a curved track, it does not move as a rigid unit. Only individual carriages are rigid, but they are connected in "joints" that can rotate. These joints or points of rotation are called turning points.

Position x

Defines the x-coordinate of the turning point.

Example:

Let us have a load pattern composed of six pairs of point forces representing three carriages. Turning points are defined in between individual carriages.

When on a straight track, the turning points have no effect.

When the train gets into a corner, the whole system of loads "breaks" in the defined turning point.
