Abstract: Based on a comprehensive analysis of the break-up and make-up practices,the capacity limit of the shunting locomotives and the relationship between the arrival and departure wagons in a railway technical station,an adjustment method for train break-up and make-up sequence was proposed. When the time for a departure train to wait for make-up is longer than or equal to the make-up time for the one following it,and its latest make-up start time is later than or equal to the earliest make-up start time for the one following it,the make-up sequence between these two trains can be adjusted. When the time for a arrival train to wait for break-up is longer than or equal to the break-up time for the one before it,and its earliest break-up completion time is earlier than or equal to the latest break-up completion time for the one before it,the break-up sequence between these two trains can be adjusted. This method could be extended to adjustment of break-up and make-up sequences among several arrival and departure trains.
