The train-set consists of one locomotive m_loco pulling 36 waggons m_waggon_tare carrying load m_load.
The train-set enters an upwards slope which causes a retardation of the locomotive which compresses the train-set.
On top of the upward slope max power on the locomotive is applied which pulls all waggons apart again.
When the acceleration wave reaches the last waggon of the train-set,
the longitudinal acceleration has grown into a level which causes sliding of its load.
Double-click directory runf/ in the subdirectory text area.
Double-click file runf/long_train_Ccoupl.tsimf in the file text area.
Press the Gplot-pushbutton.
Open file gp/long_train_Ccoupl.gp by selecting File->read_GPdat in the pulldown menu bar
Select View->view_side from the pulldown menu bar
Zoom out by pressing the left mouse button and drag the mouse downwards
Start the animation by pressing the Fwd–pushbutton.
The observer moves at constant speed Vo.
If the speed of the observer does not agree with the speed of the train-set the model can be moved longitudinally by pressing the right mouse button
and drag the mouse to the left or to the right.
Observe the last waggon and its load when the acceleration wave reaches the end of the train-set
