Liu, X. and C.T. Dick. 2019. Risk-based optimization of rail defect inspection frequency for petroleum crude oil transportation. Transportation Research Record: Journal of the Transportation Research Board. 2672 (1S): 27-35. doi:10.3141/2545-04.
The rapid expansion of production of North American petroleum crude oil from shale has led to a significant increase in rail transport of crude oil. Broken rails are frequent causes of train accidents. Ultrasonic rail defect inspection is widely used to prevent train accidents caused by broken rails, thereby reducing the hazardous materials transportation risk.…

North American freight railroads typically exhibit flexible operations with variable train schedules where freight trains are dispatched when filled to length or weight capacity, and train dispatchers resolve train conflicts in real time, making it an ideal approach for low-cost transportation of bulk commodities. Recently, North American railways have experienced a substantial decline in demand…

With installation of positive train control (PTC) on many U.S. rail corridors, Class I railroads may soon leverage these investments in communications network infrastructure to implement ‘‘advanced PTC’’ systems incorporating moving blocks. Train control with moving blocks can benefit operating strategies that dispatch fleets of multiple trains running at minimum headways. On single-track corridors with…

On single-track rail corridors, meets between trains are a significant source of train delay. From the stopping train’s perspective, a meet can be divided into three distinct phases: braking into a siding, waiting for higher-priority trains to pass, and accelerating to operating speed on the main track. Meet delay can be further divided into fixed…

Relative capacity and performance of fixed and moving block control systems on North American freight railway lines and shared passenger corridors. Transportation Research Record: Journal of the Transportation Research Board. 2673 (5): 250-261. doi:10.1177/0361198119841852.
North American railroads are facing increasing demand for safe, efficient, and reliable freight and passenger transportation. The high cost of constructing additional track infrastructure to increase capacity and improve reliability provides railroads with a strong financial motivation to increase the productivity of their existing mainlines by reducing the headway between trains. The objective of this…

Relative train length and the infrastructure required to mitigate delays from operating combinations of normal and over-length freight trains on single-track railway lines in North America. Journal of Rail and Rapid Transit. 233 (7): 731-742. doi:10.1177/0954409718809204.
Distributed power locomotives have facilitated longer heavy-haul freight trains that improve the efficiency of railway operations. In North America, where the majority of mainlines are single track, the potential operational and economic advantages of long trains are limited by the inadequate length of many existing passing sidings (passing loops). To alleviate the challenge of operating…

Freight shippers and travelers demand a consistent level of service from transportation systems, including railways. Inventory and train connections are more efficiently managed when the total time for railways to move freight or passengers between origin and destination is predictable. One approach to achieve consistency is structured operations where trains are dispatched according to predetermined…

Delayed freight trains inflict costs on many different stakeholders including the railroad, shippers, and the public. Quantifying the cost of train delay experienced by each group of stakeholders is necessary to understand the impact of a track outage or other operational disturbance, or to conduct a benefit-cost analysis to justify potential line capacity improvements.
