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. -
Irchel Tram Depot – Headshunt Redevelopment
Zurich Public Transport, Infrastructure Irchel Tram Depot – Headshunt Redevelopment 27.09.2021 Page 1 Irchel Tram Depot – Headshunt Redevelopment Client Facts Zurich Public Transport, Infrastructure Period 2010 - 2013 Project Country Switzerland Redeveloped headshunt enables Zurich Public Transport (VBZ) to operate its Irchel Tram Depot more efficiently. Difficult and time-consuming shunting tasks are now a thing of the past. Trams with low-floor cars in the middle and trailers (also referred to as “sedan-pony trams”) have been in operation on Line 7 since November 2010. These trams are now to be maintained and housed at the Irchel Tram Depot. The existing headshunt was not long enough to permit the expeditious handling of trams longer than 43 metres. Handling the 45-metre sedan-pony trams on the existing headshunt involved disconnecting the tram cars, shunting them separately into the depot and then reconnecting them – an overly complicated, time consuming and operationally impractical process. In response, Zurich Public Transport (VBZ) initiated an internal process of identifying alternative solutions. These solutions were also expected to take account of the new tram specifications that will apply following Zurich Public Transport’s purchase of a new tram generation (NTG). In October 2010, Zurich Public Transport commissioned EBP to conduct an independent and comprehensive review of the various development proposals it had worked out. The review was also to include an examination of the associated costs and relative merits of the proposed construction measures and their impact on the depot’s immediate vicinity and on railway operation in general. Working in the capacity of a general planner, EBP evaluated the various proposals and used the results of its review to outline the steps that would need to be taken to gain approval for and execute the redevelopment project. -

Camden Railway Station a Reminder of Incessant Government Under-Funding of the Nsw Rail System
CAMDEN RAILWAY STATION A REMINDER OF INCESSANT GOVERNMENT UNDER-FUNDING OF THE NSW RAIL SYSTEM These notes relate only to the history of the passenger facilities at the Camden terminus. The history of the branch line has already been published. Alan Smith, a long-time member of the Australian Railway Historical Society and a frequent volunteer at its Resource Centre, won the competition to choose the cover photo for these notes. It seems strange that Alan chose a photograph not of the terminus but of an intermediate station, Kenny Hill. Why? Alan considered that this was the “iconic image of the challenges that existed in the day-to-day operation of the Camden line”. Specifically, the photograph shows the absence of priority given to passengers when the train crew had to decide whether to convey people or freight. It should be of no surprise that people lost out. Bob Merchant took this undated photograph on a day when the steam locomotive simply could not succeed in climbing the gradient. In the composition of the train were two milk pots. They were next to the engine. There was no question of reversing the train to Narellan, shunting and then proceeding with the only the passenger car. Why not? Because the milk pots had to be attached to No. 32 Express Goods or there would be serious trouble for the train crew if the Camden milk did not accompany the other milk vans from Bowral and Menangle on the train. What! Passengers are voters. Not so much in 1963 when the line closed. -
Railway Goods Sheds and Warehouses Introductions to Heritage Assets Summary
Railway Goods Sheds and Warehouses Introductions to Heritage Assets Summary Historic England’s Introductions to Heritage Assets (IHAs) are accessible, authoritative, illustrated summaries of what we know about specific types of archaeological site, building, landscape or marine asset. Typically they deal with subjects which lack such a summary. This can either be where the literature is dauntingly voluminous, or alternatively where little has been written. Most often it is the latter, and many IHAs bring understanding of site or building types which are neglected or little understood. Goods sheds and warehouses played a significant role in the economic life of England until the 1970s. This document gives an overview of the building type from its origins in the late 1820s until the final examples were constructed in the 1960s. It considers the function and development of goods sheds, discusses elements of their design, and gives some examples of how individual railway companies developed their own distinctive styles. This guidance note has been written by John Minnis and edited by Paul Stamper. It is one is of several guidance documents that can be accessed HistoricEngland.org.uk/listing/selection-criteria/listing-selection/ihas-buildings/ First published by Historic England March 2016. All images © Historic England unless otherwise stated. HistoricEngland.org.uk/advice/ Front cover Wellingborough, Northamptonshire (listed Grade II), of a typical small goods shed. In the foreground is is exceptional in retaining both its platform and a pair the indent in the platform for carts to back into and, of 30 hundredweight timber jib cranes. Built by the MR like many sheds, the interior is whitewashed to give in 1857, it gives a good indication of the appearance more light.
