Relative Train Length and the Infrastructure Required to Mitigate Delays from Operating Combinations of Normal and Over-Length F
Original Article Proc IMechE Part F: J Rail and Rapid Transit 0(0) 1–12 Relative train length and the ! IMechE 2018 Article reuse guidelines: infrastructure required to mitigate sagepub.com/journals-permissions DOI: 10.1177/0954409718809204 delays from operating combinations journals.sagepub.com/home/pif of normal and over-length freight trains on single-track railway lines in North America C Tyler Dick , Ivan Atanassov, F Bradford Kippen III and Darkhan Mussanov Abstract 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 trains that exceed the length of passing sidings, railways preserve the mainline capacity by extending passing sidings. However, industry practitioners rarely optimize the extent of infrastructure investment for the volume of over-length train traffic on a particular route. This paper investigates how different combinations of normal and over-length trains, and their relative lengths, relate to the number of siding extensions necessary to mitigate the delay performance of over-length train operation on a single-track rail corridor. The experiments used Rail Traffic Controller simulation software to determine train delay for various combinations of short and long train lengths under different directional distributions of a given daily railcar throughput volume. Simulation results suggest a relationship between the ratio of train lengths and the infrastructure expansion required to eliminate the delay introduced by operating over- length trains on the initial route. -

Use of Ballast Inspection Technology for the Prioritization, Planning and Management of Ballast Delivery and Placement Dr
Use of Ballast Inspection Technology for the Prioritization, Planning and Management of Ballast Delivery and Placement Dr. Allan M. Zarembski, PE, Hon. Mbr. AREMA, FASME Research Professor University of Delaware Mr. Gregory T. Grissom, PE Vice President Engineering, Georgetown Rail Equipment Company Mr. Todd L. Euston, PE Senior Engineer Inspection Technologies Georgetown Rail Equipment Company Abstract This paper presents the results of a study on the optimization of ballast placement planning, prioritization and management for railway ballast distribution. Specifically, this paper presents the requirements for and inputs necessary to more effectively manage the ballast placement process and take advantage of the new track inspection technologies that provide more accurate and reliable data about ballast condition and track profile. This is to include addressing such key issues as: Where and how much ballast should be placed; to include ballast at end of ties (shoulders), under ties, and in cribs. How much ballast should be placed; to include reference or required ballast profile based on vertical, lateral and longitudinal performance requirements A key portion of this study was the introduction of new inspection technologies now available to more accurately define the ballast requirements. This includes such newly introduced inspection technologies as LIDAR for measurement of the ballast profile, Ground Penetrating Radar inspection for ballast depth deficiency, and other related inspection technologies. This in turn allows for more accurate ballast deficit analysis and calculation to include the reference or “ideal” profile used to determine the ballast deficit and the calculation of the difference between the current profile and this reference profile, which includes vertical load distribution and lateral and longitudinal restraint requirements. -

Longitudinal Track-Ballast Resistance of Railroad Tracks Considering Four Different Types of Sleepers
Longitudinal Track-Ballast Resistance of Railroad Tracks Considering Four Different Types of Sleepers Rudney C. Queiroz São Paulo State University, Bauru (SP), Brazil Abstract This paper aims at studying the behavior of a railroad track concerning the action of longitudinal forces, targeting the determination of the track-ballast resistance, in a real scale standard track model. This research, was developed at the São Paulo State University, and consisted of a comparative study of track- ballast resistance for railroad tracks built with four different types of sleepers. The first set of sleepers was made of steel, the second one was made of wood, the third one of prestressed-concrete and the fourth one of two-block concrete. In order to carry out this research, four 1600 mm gauge models were built with two TR-68 rails, fastened to seven sleepers by means of elastic fasteners and base plates. The sleepers, all of the same type for each model, were embedded in 0.35 m thick ballast, which was supported by a layer of 30 cm thick compacted soil. The computerized data acquisition system allowed displacement and force values to be obtained in real time. By convention, the maximum longitudinal track-ballast resistance corresponds to a displacement of 15 mm. The prestressed-concrete sleeper setup showed the greatest longitudinal track-ballast resistance per sleeper. The second best performance was obtained by the two- block concrete sleeper setup, followed by the wooden and the steel sleeper setups. The force- displacement curves showed an exponential rise to a maximum shape. The displacement corresponding to the maximum track-ballast resistances were different for each kind of sleeper setup. -

Structure Gauge Measuring Equipment Using Laser Range
PAPER Structure Gauge Measuring Equipment Using Laser Range Scanners and Structure Gauge Management System Takashi TOYAMA Signalling Systems Laboratory, Signalling and Transport Information Technology Division Nozomi NAGAMINE Image Analysis and IT Laboratory, Signalling and Transport Information Technology Division Tatsuya OMORI Kenichi KITAO Signalling Systems Laboratory, Signalling and Transport Information Technology Division (Former) Ryuta NAKASONE Image Analysis and IT Laboratory, Signalling and Transport Information Technology Division Periodic measurement of the structure gauge is essential to ensure safe train operation. Measuring the clearance gauge however, is time and labor intensive given the vast number of trackside facilities. An inexpensive and efficient measuring device using laser range scanners was therefore developed. A management system is also being developed, which maps mea- sured three-dimensional point cloud data to facility data. This paper describes the problems and solutions related to applying the laser range scanners for structural gauging, and pres- ents results obtained from experiments.
