RailTEC Presentations at 2020 INFORMS Annual Meeting

Three members from the RailTEC Systems Group participated in the 2020 Operations Research and the Management Sciences (INFORMS) annual meeting, which was held on Saturday, 07 November – Friday, 13 November.  RailTEC Lecturer and Principal Railway Research Engineer, C. Tyler Dick was a session chair for the Yards and Terminals session on Monday and also presented his research on “Influence of Mainline Schedule Flexibility and Volume Variability on Railway Classification Yard Performance”.

In the same Yards and Terminals session, Jiaxi Zhao, RailTEC Ph.D. student, presented her work on “Hump Yard Performance Simulation with Anylogic”.

On Tuesday attendees listened as Geordie Roscoe, RailTEC M.S. student, spoke on the subject of “Deadlock Avoidance Dispatching Algorithm for Generalized Track and Train Configurations” in the Railway Resource and Management and Optimization session.

This was the first entirely virtual annual meeting and was a combination of live and on-demand sessions with live Q&A.  Each year the INFORMS Annual Meeting draws thousands of operations research and analytics professionals, students, industry leaders and more from across the globe for unique opportunities for face-to-face learning, networking, and collaboration.

Virtual Railroad Environmental Seminar Wrap-up

The Virtual Railroad Environmental Seminar (vRRES) on 27 – 28 October 2020 was a resounding success with over 450 registrants from 14 countries and five continents. In addition to the outstanding technical presentations, it was noted that the seminar showcased the growing number of women in the field and provided them with an outreach and networking opportunity. This year women made a significant impact by being over half of the presenters (including the keynote speaker), the chair of the Environmental Affairs Committee and half of the nominees (and the winner) for the AAR Environmental Excellence Award.

Robert Fronczak (L) with the winner of the 2020 AAR Environmental Excellence Award, Meaghan Atkinson (R) of CSX.

The AAR Environmental Excellence Award is the industry’s highest honor for environmental professionals and was awarded by Robert Fronczak, AAR, to Meaghan Atkinson of CSX. She is a manager of environmental programs at CSX and leads the railroad’s effort to implement some of the most ambitious greenhouse gas targets in the transportation sector. In addition to Atkinson, seven other railroad environmental professionals were nominated for the award. They were Laura Fotiou of Amtrak, Karla Graf of CN, Tara Hill of Kansas City Southern, Josh Raglin of Norfolk Southern Railway, Joel Strafelda of Union Pacific Railroad, Sean Strong of Watco Cos. LLC, and Nic Winslow of BNSF Railway Co.

Recordings of the seminar presentations will be made available to registered attendees on Thursday, 5 November 2020 for one month. After a one-month viewing period, recordings of authorized presentations will be posted to the RailTEC YouTube Channel and will be available to the public. See the full seminar program here.

Mark your calendars now for next year’s Railroad Environment Conference (RREC) on 2-3 November 2021.

Riley Edwards ASLRRA Webinar Speaker

One of the guest speakers for the Thursday, 29 October 2020 American Short Line and Regional Railroad Association (ASLRRA) webinar was J. Riley Edwards, RailTEC Senior Research Scientist and Senior Lecturer. Riley presented on the topic “Using 3D Lasers & AI Innovations in Track Inspection” with Cam Stuart, Program Manager, Office of Research, Development, and Technology, Federal Railroad Administration (FRA) and Richard Fox-Ivey, Principal Consultant, Rail Industry, Railmetrics.

This webinar described the field deployment and validation of a new approach being developed in partnership with the FRA that could help railroads with track inspection. This new approach pairs three-dimensional (3D) machine vision with Artificial Intelligence (a deep convolutional neural network) and change detection technology.  The speakers presented details relating to the process for 3D image capture on the High Tonnage Loop at TTCI, training the Artificial Intelligence for feature identification, and the detection of changes related to clips, spikes, end of tie ballast levels and joint bar bolting between repeat runs.

INFORMS RAS International Webinar Speaker – Tyler Dick

The speaker for the Wednesday, 21 October 2020 INFORMS Railway Applications Section (RAS) International Webinar Speaker Series was C. Tyler Dick, RailTEC Lecturer and Principal Railway Research Engineer. Over 80 online participants listened as Tyler presented “Network Efficiency Cycle: Quantifying Yard and Mainline Railway Capacity and Performance Connections”.  His presentation summarized research to understand and quantify relationships between the capacity and performance of both classification yards and mainlines, these disparate yet complementary facilities. This was the fourth online webinar in the RAS International Webinar Speaker Series which was organized to feature operations research and advanced analytics applications and good practices in the railway industry with speakers from both academia and industry.

RailTEC Student Awarded Inaugural Scholarship

RailTEC graduate research assistant, Lee Evans, is an inaugural recipient of a Railway & Locomotive Historical Society (R&LHS) scholarship. Four awardees received R&LHS scholarships this year, which are named in honor of the R&LHS members who made the scholarships possible. The awardees are graduate and advanced undergraduate university students studying aspects of railroad history and operations.

Lee, who has extensive experience in railroad museum operations, received a George W. Hilton scholarship. Hilton was an economics professor at UCLA, and an accomplished historian, writing a number of books on railroads and ships. He died in 2014 at age 89.

The R&LHS scholarship program is open to students majoring in history and transportation/transportation logistics, or other majors where the student’s work has a demonstrated connection to railroad operations and history. Applications open January 1 and must be submitted by March 31. Recipients are notified at the end of June.
