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. -

Colchester – Package 1 Share with Pride
Colchester – Package 1 Share with Pride 23-Jul-14/ 1 Colchester Station – Project and Planning History PROJECT SCOPE Colchester Station is a key interchange on the Great Eastern Mainline (LTN1) and is historically difficult to block for engineering access. The route through Colchester carries mixed traffic, with large commuter numbers, the single point of access for Electric Freight to Felixstowe Port and a growing leisure market at weekends. The original scope was to deliver 36 Point Ends in Modern Equivalent Form and circa 4100 Linear Metres of Plain Line. The primary driver for the renewal was poor ballast condition leading to Track Quality issues and the associated performance issues. TRACK ACCESS The renewal work for the S&C and PL at Colchester was originally proposed to be delivered a number of years earlier (some elements as long ago as 2008/9). The original planning workshops with the Route, National Express and the Freight Operating Companies explored different vehicles for delivery: - 2x 8 Day Blockades – to complete all works. -1x 16 Day Blockade – to complete all works. - A series of “conventional” 28 and 52 hour Possessions – totalling 26x 52 hour weekends spread over 2 years. These options were discussed in detail with the TOCs and FOCs. There were a number of caveats concerning a blockade strategy. The FOCs would still have had to pass trains through Colchester due to a lack of capacity on the non electrified diversionary route and the TOCs requested to run a service in from both Country and London through the midweek elements of the blockade due to the physical number of passengers they needed to move. -
