In the last ten years, the railways generally throughout the world have suffered a decline in their share of the transportation market relatively to other modes of transportation. This has meant a serious loss of business which has led to many financial difficulties. This loss of a share of the market has come about despite the lasting importance of the railways generally in the economy, despite their necessity in economic development and despite their continued progress in technology. Should the railway situation continue to deteriorate, transportation systems could be endangered seriously. In this thesis, a reform of railway pricing policies is proposed as an important contribution to the solution of the present railway problem. [...]

The Crowsnest Pass rates are fixed rail freight rates that apply on the carriage of most Canadian grain. They were originally established in 1897, and have been embodied in Federal statute since 1925. In recent years, the rates have covered less than 40 percent of rail-grain costs. With continuing cost inflation, this proportion will decrease to even lower levels over time. Several policy alternatives are available to the Federal Government with respect to the transportation of grain by rail. These alternatives are characterized primarily by different freight rate levels. The lowest rate level considered herein is the current one; the highest is a level at which the railways would recover the long-run variable costs of the rail-grain system plus a contribution to their constant costs. For each price-level alternative, there are a range of subsidy alternatives. Depending on the particular price level, subsidies could be given to the railways, the grain producers, neither of these, or both of them. In order to evaluate the policy alternatives, there must be criteria for evaluation. The criteria used in this thesis are the major objectives that relate to the issue. Two of the objectives are to improve economic efficiency and to facilitate the development of secondary industry in the Prairie provinces. Both of these objectives favour the pricing alternative of raising grain freight rates to a compensatory level. Without producer subsidies, however, this alternative violates a third objective--that of minimizing grain-producer transportation costs. In addition to these three objectives, there are four objectives that refer particularly to the Federal Government. They are maximizing votes, implementing the "user pay" philosophy, minimizing total subsidy payments, and assisting railway variable-cost recovery in grain transport. A major consideration that is not an objective is the resistance of producers to direct, rather than indirect, subsidies. The quantitative impacts of raising rail-grain rates on the railways and on grain producers are substantial. Implementing rail freight rates equal to the long-run variable costs of transporting grain would have increased the combined net revenue of the Canadian National Railways and CP Rail by at least two-thirds in 1976. It would have decreased the net income of Prairie grain farms by (at most) 15 percent in the same year. Two policy alternatives are chosen as the better alternatives. The first policy selected is that of initial Crowsnest Pass rates, increasing over time to a larger and larger proportion of rail-grain costs. This pricing scheme would be accompanied by constant railway subsidies to reflect the difference between costs and revenues. The second policy is an immediate increase to rates covering variable costs, with subsequent annual increases to adjust for inflation. With this pricing policy, there would be constant producer subsidies equal to the initial rate increase. / Business, Sauder School of / Graduate

Thesis (MTech (Business Administration in Project Management))--Cape Peninsula University of Technology, 2019. / This study focussed on the evaluation of quality management at one of the selected South African freight rail construction projects. Transnet Freight Rail (TFR) was selected for its high rate of accidents and injuries that happen on daily basis which affect the company’s operations and profits. The study’s approach was to obtain as much as possible opinions from local and international experts on quality management in construction projects. The opinions were gathered through a number of official journals on the best practices for quality management, comparing all of these practices to that of TFR in order to conclude whether the need for improvement or the change in practicing quality is required. The mixed − method approach was employed, to gather more and accurate data. The strengths of qualitative research approach can make up for the weaknesses of the quantitative research approach, this was the reason why mixed − method was chosen. The targeted population of this study included the internal stakeholders such as quality assurance officers, project managers, project coordinators and project team members. This targeted population was able to provide the accurate information as they are directly involved in the execution of the projects in terms of quality management of the project. A questionnaire was developed and employed as a tool to gather data to satisfy the research questions. This study was a case study because it only focused on TFR Iron Ore line projects. The focus was that, within TFR Iron Ore line, only those who are affected directly by the above mentioned projects were interviewed. The study has revealed that the Total Quality Assurance measures are being ignored at TFR, such as unscheduled quality tours, quality audits, quality control routines, random sampling of errors and record seen defects, and quality monitoring throughout the project life cycle.

The material properties of the candidate fiber-reinforced composite materials and different fabrication methods for fiber composites were discussed. The improvement of the hand lay-up process for polyurethane impregnated Kevlar was investigated. Testing samples for lab and prototype tests were fabricated by hand lay-up process. The study showed that fiber composites fabricated by the hand lay-up process can achieve good properties, and advanced fabrication methods could be applied In industrial manufacturing processes to improve the fiber composite properties. A nonlinear static analysis was discussed. The ANSYS finite element analysis computer program was used to build stress analysis models, simulate the loading conditions, and perform the nonlinear static analysis. The tensile strength proof test was designed and done by using a microcomputer controlled Instron 4505. It showed that the different types of fiber composites can meet the strength requirements for the application. Polyurethane impregnated Kevlar showed the best strength properties among the different types of fiber composites, which were fabricated and tested. The wear and abrasion properties of the different types of fiber composites were discussed and relevant tests were introduced. An ultraviolet light exposure test and the Oregon Department of Transportation road-cover test were conducted. Moisture and acid resistance and cost analysis were also discussed. Based on the results of the study, a prediction of the optimal fiber-reinforced composite materials was made. Also, various conclusions and recommendations for future research work were made. / Graduation date: 2000
