Recently the FRA has proposed a reduction in the maximum allowable net axle lateral load limit from the current 50 percent of static vertical axle load (NAL/V limit = 50%) to less than 40 percent depending, in part, on the basis of FRA’s lateral track strength model, TREDA. Such a reduction could indirectly result in limiting the maximum speed of high speed passenger trains to the equivalent of 7 inches (178 mm) cant deficiency. This paper reports on the author’s investigation of selected assumptions and calculations made in TREDA. Improvements to the model are recommended and a revised NAL/V relationship is proposed, derived from an independent analysis of the driving and resisting forces. Finally, a vehicle dynamic analysis is performed to determine how the author’s proposed revised NAL/V limit would affect 9-inch (229 mm) cant deficiency operation as the high speed rail industry is now considering.

Based on the analysis of the high-speed rail industry chain, first, this paper divides the high-speed rail industry chain into infrastructure construction market and manufacturing market of mobile equipment and, second, this paper uses the empirical method of new experience industry organization to measure the market power premium of the high-speed rail upstream market. The study shows that the market power premium of the high-speed rail upstream market is 0.551, and the scale elasticity is 0.314, indicating that there is no systematic market power in the high-speed rail upstream market and there is significant scale diseconomy. The vertical market structure where “private enterprises dominate the upstream competition market and state-owned enterprises dominate the downstream oligopoly market” is further established. Based on the perspective of enterprises’ entry in upstream markets, the social welfare of the high-speed rail industry market structure is analyzed. It is found in the study that the upstream market of the high-speed rail industry has a tendency of insufficient enterprise entry, and the total social welfare increases with the increase in the number of upstream enterprises entry. What is more, the profit of enterprises in the upstream market of high-speed rail decreases with the increase in the number of enterprises in the upstream. This paper believes that policies such as stimulating upstream high-speed rail enterprises entry, providing subsidies to upstream enterprises, reducing upstream enterprises’ entry barriers, and expanding international markets can effectively improve the overall social welfare of the high-speed railway industry.

Rail Services

This research uses a two-way fixed effect model to examine the correlation between the development of high-speed rail and the growth of green technology innovation by adopting the panel data of 284 Chinese cities between 2004 and 2013. The empirical results show that the supply of high-speed rail services has a significant promoting influence on the advance of urban green technology innovation capabilities. In particular, cities located in central and western China, along with those cities with relatively little government support or relatively backward public cultural infrastructure, have more chances to benefit from the supply of high-speed rail services. In addition, by employing a mediating effect model, this article finds that the industrial collaborative agglomeration plays an important mediating role between high-speed rail and regional green technology innovation. Therefore, this article suggests that the Chinese central government should continue to accelerate the construction of the rapid transportation network and expand the coverage of high-speed rail services in China to increase the growth of green technology innovation and achieve steady and sustained economic growth in China. Meanwhile, local governments should actively guide the collaborative agglomeration of manufacturing and related producer service industries under local conditions to stimulate the expansion of the green technology innovation market.

In countries with government-owned railways, the subsidies required to maintain service were becoming a serious burden on the state. Declining revenues have left the rail industry struggling to overcome operating deficits and to reduce subsidies from governments. This study aims to analyze the financial performance of Indonesia and Taiwan urban rail system. Financial ratios are employed to measure the profitability, liquidity, activity, and solvency performance of PT. Kereta Api Indonesia (KAI) and Taiwan High Speed Rail (THSR). The data were collected from both companies in the period of 2011-2015 based on its audited inancial report. In addition, the Decree No. KEP-100/MBU/2002 issued by Indonesia Ministry of SOEs was used to validate the inancial health condition with the level of financial assessment. The result showed that KAI had better financial performance in comparison with THSR. Generally, both companies have a challenge in asset utilization and inventory management. Therefore, this study is useful for the managers to tackle the challenges and improve its eficiency. Furthermore, this study could be policy options might be taken to improve both urban railways' performance.
