Using Simulation to Make Hump Yard Capital Expense Decisions
The Belt Railway of Chicago
Belt Railway of Chicago’s (BRC) Clearing Yard is among the largest hump yards in United States. BRC spends millions of dollars annually in projects aimed to increase capacity, reduce cost or improve efficiency. We developed a hump yard simulation system for BRC to use when making these decisions.
- YardSYM’s® enabled Belt Railway of Chicago to make informed major capital expense decisions.
- Thanks to YardSYM’s® animation of train operations in the yard, yard managers were able to identify the causes for yard congestion and to determine their solutions.
- To reduce the time between two consecutive train arrivals, YardSYM® suggested that a pair of receiving tracks should be extended up to the hump. This would improve the yard dwell by as much as 15 percent, if the yard’s volume were to increase by 10 percent or more.
By using YardSYM®, we recommended that BRC change manual switches to power switches and add several class tracks to increase throughput and improve service. YardSYM® helped identify the ideal configuration of tracks connecting the class yard to the departure yard, which had been the capacity bottleneck for the yard. With YardSYM®, we evaluated how effectively the new layout in the receiving and departure yards would be used once the new mainline tracks were laid out through the yard.
