铁路货车可靠性试验方法及评价标准的研究

在中国铁道科学研究院环行试验基地进行的历时5年的提速货车120 km.h-1可靠性试验的基础上,结合运营线试验分析,提出铁路货车可靠性试验方法:参试车辆应具有代表性;试验线路应具有典型性,并设置一定的线路不平顺;试验里程为1至2个段修期;最高运行速度的试验里程不应低于总里程的60%。在分析测试结果、故障分布及车辆可靠性指标和铁路货车关键部件的疲劳特性的基础上,依据故障的严重程度和对车辆维修的影响,对故障进行分类与加权,计算货车的平均无故障时间和故障率,并进行评价;将落车时实测的静应力与运行中测得的动应力叠加并用Goodman方程转换,得出以对称循环表征的疲劳等效应力,结合对称循环概率疲劳等效应力和部件细节对称循环的概率应力—寿命曲线,通过Miner线性累积损伤法实现转向架关键部件疲劳寿命的可靠性预测。

Individual freight effects,capacity utilization,and Amtrak service quality

This paper offers a new perspective on the post-deregulation rail industry. We hypothesize that a link exists between individual freight effects and Amtrak service quality. Specifically, we investigate the relationship between freight control of the infrastructure on which Amtrak trains operate and Amtrak train delays. Our sample consists of 1117 directional station-pairs for fiscal years 2002 through 2007 on 28 Amtrak non-Northeast Corridor passenger routes. We found that freight effects have a significant impact on Amtrak train delays after controlling for other important delay determinants such as the capacity utilization rate. The impact is higher on long-distance routes. We also observed significant differences between the effects of different freight railroads. For example, Amtrak operations on infrastructure controlled by several Class I railroads experienced significantly larger delays than baseline operations, while Amtrak train delays on Burlington Northern and Santa Fe’s tracks actually fell below baseline levels.     

The possible designation of the Mediterranean Sea as a SECA: A case study

In view of the ongoing discussions concerning the possible designation of the Mediterranean Sea as a Sulphur Emission Control Area (SECA), a modal split model was applied to a case involving the transportation of consolidated cargoes between Thessaloniki, Greece and industrial hubs of northern Germany. A road-only option was assessed against a combined-transport route involving a ferry (Greece–Italy) and a truck-on-train (Italy–Austria) service. The logit model used considers two variables as determinants of the modal selection: transport cost and time. The data are derived from interviews with a small transport service provider, typical for Greece, and are based on actual trips made (revealed preferences). The results predict that the designation of the Mediterranean as a SECA will cause a modal shift in favour of the road-only route by 5.2%, which under certain assumptions can reach 17.1%. However, the environmental implications of the resulting modal choices, calculated through the EcoTransIT World web based tool, are positive in relation to all emissions examined. This is attributed to the longer distance of the combined-transport option in comparison to the road-only one and, the poor environmental performance of the Ro-Pax vessels basically due to the need to maintain a relatively high speed.
