# This is an example script for a JMRI "Automat" in Python
|
|
# It is based on the AutomatonExample.
|
|
#
|
|
# It listens to two sensors, running a locomotive back and
|
|
# forth between them by changing its direction when a sensor
|
|
# detects the engine.
|

# Author: Howard Watkins, January 2007.

# Part of the JMRI distribution
