# Sample script that will set a wait value for all cars in a specific train.
|
|
# Useful if you want the cars set out by the train to remain unavailable for
|
|
# other trains. A wait value of 1, means the next train built will not use
|
|
# cars from this train.
|
|
#
|
|
# Use this script after the train has been built.

|
|
# To use this script you must assign the train that you want the cars waited,
|
|
# and the wait value.
