After a brief outline of freight rail operations planning, the paper reviews the research and development of optimization and simulation tools to undertake train planning, train and locomotive scheduling, as well as track maintenance planning. Although optimum solutions can be obtained using such tools, they have not been widely embraced by rail organizations. The simplifying assumptions made by most models make their practical application difficult to achieve. Whilst drawing on overseas research, the paper focuses mainly on the Australian experience for operations planning practice. Freight rail market share increases are closely related to the level of service offered, particularly in transit times and reliability of arrivals. Both these two levels of service attributes are associated with track infrastructure design and maintenance ...
As privatisation of railway systems reach the political agendas in a number of countries, the separation of track infrastructure from train operations is seen as providing the vehicle which will improve profitability within the rail industry. This paper deals with three main issues related to such separation within a freight railway focus, namely: investment appraisal; track standards and maintenance; and train operating performance. The conflicts of interest between the owners of track and their client operators are discussed in detail. Costs related to track capacity and congestion need to be taken into account, given that additional trains are likely to lead to increased risk of delays to existing services. The paper discusses the use of a travel time reliability model to estimate the additional costs imposed on the system thr...
E-business is defined here as encompassing both e-commerce and the application of information technology to link internal and external business operations - Business to Business (B2B). The findings reported here are the results of a recent Australia-wide study undertaken for a Federal Government Transport Agency. The study was intended to assist Australian business and government to pro-actively address the transport issues arising from e-business. The main aims were to undertake an analysis of the main transport impacts of e-business and to quantify those impacts on the different stakeholders at the national and regional levels. The Seminar will highlight the study methodology used to derive changes in demand from e-business take-up. The main study findings, in terms of likely changes in freight and passenger demand will be pres...
