    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.

  • Union Depot Tower Interlocking Plant

    Union Depot Tower Interlocking Plant

    Union Depot Tower Union Depot Tower (U.D. Tower) was completed in 1914 as part of a municipal project to improve rail transportation through Joliet, which included track elevation of all four railroad lines that went through downtown Joliet and the construction of a new passenger station to consolidate the four existing passenger stations into one. A result of this overall project was the above-grade intersection of 4 north-south lines with 4 east-west lines. The crossing of these rail lines required sixteen track diamonds. A diamond is a fixed intersection between two tracks. The purpose of UD Tower was to ensure and coordinate the safe and timely movement of trains through this critical intersection of east-west and north-south rail travel. UD Tower housed the mechanisms for controlling the various rail switches at the intersection, also known as an interlocking plant. Interlocking Plant Interlocking plants consisted of the signaling appliances and tracks at the intersections of major rail lines that required a method of control to prevent collisions and provide for the efficient movement of trains. Most interlocking plants had elevated structures that housed mechanisms for controlling the various rail switches at the intersection. Union Depot Tower is such an elevated structure.

Tower was owned and operated by the four rail companies with lines that came through downtown Joliet.

Background This technical note explains the speed related risk criteria to be considered during the buffer stop design stage. It provides amendments to the maximum allowable deceleration rate for lighter weight rolling stock while complying with the allowable impact force requirements. This technical note also provides amended maximum allowable impact force that the newer generation trains can accommodate without any damage. These figures shall be used by all parties undertaking review or design of new buffer stops across the Metropolitan Rail Area. 2. Section 12 Risk assessment Insert the following after the third paragraph: In order to establish the nature and extent of damage upon collision, the risk assessment for a buffer stop design shall consider the possibility of a train travelling at a speed higher than the design speed and the expected consequential damage upon collision. In the SFAIRP justification, an indication shall be provided to indicate the following: • Up to the design speed that no permanent damage will occur to the train. The buffer stop will be fully recoverable, either automatically or within simple maintenance actions. • Up to the 'worst case speed' that the damage will be easily reparable; for example, easy repair or replacement of buffer stop parts.
