A) User request
A certain kind of train
- should stop on demand at several railway stations.
The stop request may be given
- by a button inside the train and additionally
- by a button on each platform.
B) Solution details

- Demand-stop locomotives are of Rocrail locomotive type "Light".
- The locomotive function for a demand-stop is named "dstop".
- The blocks bk01, bk02 and bk03 are connected by two routes. One route for the standard locomotives and one route for the demand-stop locomotives.
- Stopping for locomotives is done by locking the next demand-stop route.
- The demand-stop request from inside the locomotive is done by an action that sets the platform demand-stop button to ON. The action is executed by an ENTER event from blocks bk01, bk02 and bk03.
- Resetting the buttons is executed by an IN event from blocks bk01, bk02 and bk03.
The Rocrail actions
These actions hand the internal demand-stop request to the external platform demand-stop request. This is working because the actions are executed before the next route is set.
| Action | condition | executed by | content |
|---|---|---|---|
| ac_dstop_bk01_set | locomotive is of type "Light" AND locomotive's function "dstop" is ON | block bk01 at ENTER | set fb_dstop_bk01 to ON |
| ac_dstop_bk02_set | locomotive is of type "Light" AND locomotive's function "dstop" is ON | block bk02 at ENTER | set fb_dstop_bk02 to ON |
| ac_dstop_bk03_set | locomotive is of type "Light" AND locomotive's function "dstop" is ON | block bk03 at ENTER | set fb_dstop_bk03 to ON |
This action switches off the internal demand-stop request as soon as the locomotive has stoped on demand:
| Action | condition | executed by | content |
|---|---|---|---|
| ac_lc_light_dstop_off | locomotive has speed "V0" AND sensor fb_dstop_bk01 is ON | block bk01 at IN | set fb_dstop_bk01 to OFF |
| locomotive has speed "V0" AND sensor fb_dstop_bk02 is ON | block bk02 at IN | set fb_dstop_bk02 to OFF | |
| locomotive has speed "V0" AND sensor fb_dstop_bk03 is ON | block bk03 at IN | set fb_dstop_bk03 to OFF |
These actions switch off the external demand-stop request as soon as the locomotive has stoped on demand:
| Action | condition | executed by | content |
|---|---|---|---|
| ac_dstop_bk01_reset | none | block bk01 at IN | set fb_dstop_bk01 to OFF |
| ac_dstop_bk02_reset | none | block bk01 at IN | set fb_dstop_bk02 to OFF |
| ac_dstop_bk03_reset | none | block bk01 at IN | set fb_dstop_bk03 to OFF |
These actions are used to run the locomotives alternativly. Both locomotives have to be startet at first and one signal has to be set to green/yellow to run the first locomotive.
| Action | condition | executed by | content |
|---|---|---|---|
| ac_sg04_green | none | block bk14 at IN | set signal sg04 to green |
| ac_sg14_yellow | none | block bk04 at IN | set signal sg14 to yellow |
C) The Workspace
The download workspace " demand_stop.zip" contains the following files:

back to Solution details.
Open the workspace
- start automatic mode
- start both locomotives (if available in virtual mode)
- set one signal (sg04 or sg14) to green/yellow
- use one of the demand-stop buttons to check its functionality.
Have fun.
