Guest Seminar 11/14
On November 13-14, 2024, TRAIN was excited to host a visit from Dr. Riley Edwards, Assistant Professor, University of Illinois Urbana-Champaign, who gave a seminar entitled “Leveraging Emerging Railway Track Health Data for Track Condition Assessment and Buckle Risk Hot Spot Detection”. It was great to see Riley and learn more about his ongoing research while discussing plans for collaboration through the new FRA-sponsored National University Rail Center of Excellence. Both UIUC RailTEC and the UT TRAIN Lab are members of this exciting new academic railway research, education and technology transfer consortium.
Fall Conference Round-Up
It was a busy fall semester of conferences for TRAIN faculty and students!
In September, Prof. Dick travelled to Louisville, KY to attend the AREMA Annual Conference and Chair the meeting of AREMA Committee 16 (Economics of Railway Engineering & Operations).
In October, Prof. Dick travelled to the American Short Line and Regional Railroad Association Eastern & Southern Region Meeting held in Jacksonville, FL to present on the challenges and opportunities of alternative energy locomotive development in the shortline and regional railway context.
Later in October, Prof. Dick and TRAIN doctoral students Qianqian Tong and Steven Shi travelled to the INFORMS Annual Meeting in Seattle, along with several other members of the UT Transportation Group. Qianqian presented on her work to optimize the layout of inland truck-rail intermodal terminals. Steven presented on his work to evaluate the optimal deployment of battery electric locomotives across different battery sizes, route characteristics, train properties, and charging strategy. Prof. Dick also presented on TRAIN graduate Jiaxi Zhao’s research to model railway network dynamics with multi-yard simulation and mainline interaction.
At the same time, TRAIN doctoral student Rydell Walthall presented on his research to evaluate the costs and benefits of modern options for freight railway electrification at the NEMA Railroad Electrification Coalition meeting in Arlington, VA. Later in October, Prof. Dick presented on this same research project at the 26th Railroad Environmental Conference held in Urbana, IL.
Finally, in early November, prof. Dick had the honor of travelling to the University of Illinois Urbana-Champaign to deliver an invited WW Hay Railroad Engineering Seminar on Modeling the Economics of Modern Options for Mainline Freight Railway Electrification.
New Journal Publication!
Excited to announce that TRAIN PhD student Jiaxi Zhao and Prof. Dick have recently published a new research paper in the IET Intelligent Transportation Systems academic journal! This paper investigates how classification yard simulation can supplement historical operating data in making improved predictions of delayed freight train departures. A unique aspect of this paper is that it was developed through our international collaboration with railway researchers at KTH Royal Institute of Technology in Sweden. We’ve enjoyed our long-term collaboration with Niloofar Minbashi and Markus Bohlin at KTH, including a trip to visit them in Stockholm in summer 2022!

New Journal Publication!
Excited to announce that TRAIN PhD student Jiaxi Zhao and Prof. Dick have recently published a new research paper in the Transportation Research Record academic journal! This paper presents the application of newly developed framework to quantify the relative derailment risk of transporting hazmat tank cars in unit trains and manifest trains, including the effect of position in the train and the number of intermediate classification yards used by the manifest train shipment.

Long Trains Study Released
Since late 2022, Prof. Dick has been serving on the National Academies of Sciences, Engineering and Medicine consensus committee studying the impacts of longer freight trains. The Final Report of the consensus committee was released on September 17th by the Transportation Research Board.
The Final Report, entitled “Long Freight Trains: Ensuring Safe Operations, Mitigating Adverse Impacts” can be accessed at the following link: https://doi.org/10.17226/27807.
Summer Conference Round-Up
It was a busy summer of conferences for TRAIN faculty and students!
In May, TRAIN doctoral students Rydell Walthall and Steven Shi travelled to the ASME/IEEE/ASCE Joint Rail Conference in Columbia, SC. Rydell presented on his work to model and optimize partial railway electrification using overhead catenary and batteries. Steven presented on his work to model the sensitivity of diesel fuel savings from battery electric locomotive deployment.
In June, Prof. Dick travelled to Atlanta to chair sessions at the ASCE International Conference on Transportation & Development. He also made two presentations, one on ongoing research for Parallel Systems on self-propelled autonomous railcars for transporting shipping containers, and a second presentation on ongoing work with Michigan Technological University to development a framework for LCA of track maintenance material and activity emissions.
Finally, in August, Prof. Dick travelled to Livonia, MI (outside Detroit) to present at the Michigan Rail Conference. His talk addressed the challenges of creating capacity for passenger operations on freight rail corridors.
New Journal Publication!
Excited to announce that TRAIN PhD student Steven Shi and Prof. Dick have recently published a new research paper in the Transportation Research Record academic journal! This paper is related to Steven’s work to investigate the adoption of heavy axle loads by US freight railroads to transport different commodities.
The reference and DOI link for the paper is as follows:

Dr. Dick goes to Washington
In June, Prof. Dick travelled to Washington DC to provide expert testimony to the US House Committee on Science, Space & Technology. The committee’s Investigations & Oversight Subcommittee held a hearing entitled “Environmentalism Off the Rails: How CARB will Cripple the National Rail Network“. A video of the hearing, including Prof. Dick’s testimony on the operational limitations and development and deployment challenges of alternative energy locomotives technology for mainline freight rail applications, can be found here: https://youtu.be/V8Wth0Zj7zA
New Journal Publication!
Excited to announce that TRAIN students Geordie Roscoe and Matt Parkes, along with Prof. Dick have recently published a new research paper in the Transportation Research Record academic journal! This paper is related to their work on initial operational modeling of platoons of battery-powered, autonomous, Parallel Systems rail vehicles to transport intermodal shipping containers on low-density short-haul corridors.
The reference and DOI link for the paper is as follows:

Congratulations Dr. Zhao!
Congratulations to TRAIN PhD student Jiaxi Zhao on successfully defending and depositing her Doctoral dissertation! As the first TRAIN PhD graduate, her dissertation is entitled “Simulation of Hump Classification Yard Performance: Railway Network Resiliency and Operational Consequences of Yard Disruptions and Derailments”. We’ll miss Jiaxi as she graduates to a career in the rail industry!
