巴基斯坦ML-1线罗赫里站升级改造方案研究

为解决既有ML-1线罗赫里站存在的正线技术标准较低、车站咽喉区布置凌乱、到发线长度不足和站场设备陈旧等问题,通过分析罗赫里站场条件,提出罗赫里站升级改造方案,提出将车站由直线站改造为曲线站,对既有罗赫里站站东咽喉外方反向曲线进行局部改造,延长夹直线作为咽喉区,延长了罗赫里站站坪长度。在此基础上,分析确定到发线规模、车站平面设计、横断面布置,增加旅客列车到发线、旅客站台等设施,对咽喉区进路布置进行优化,实现罗赫里站正线贯通布置。

基于配流方案的树枝形专用线取送车时机的确定

由于每个车站设备条件、作业组织方法、车流性质等各不相同,难以用一种通用的模型来描述车站的取送车作业问题。我国大多数编组站的专用线都采用树枝形布置形式,因此以此为例,依据货场、专用线有无合适去向的车流等情况,结合车流到发的不同方式分为取车和送车两个过程,并分别给出合理取送车时机的计算方法。

Attracting travellers to the high-speed train: a methodology for comparing potential demand between stations

The High-Speed Railways (HSR) which are currently operative in 12 countries throughout the world include a wide range of stations with a highly varied capacity to attract travellers. Although there are various reasons for these differences, we have focused on the ones that can be quantified for further comparison. The main purpose of this study was twofold. First of all, we sought to identify stations with a low capacity to attract travellers and to explain the reasons for their concentration in certain countries rather than others. Secondly, we looked for a simple, but widely acceptable, method with which to calculate the capacity to attract users to HSR stations. This would help to establish a better way of allocating financial resources for public investment. This approach enabled us to identify those stations that had little or no potential at all and which had been established for essentially political reasons in countries where the concept of territorial cohesion had been applied in an inappropriate way. This led us to a number of observations relating to the railway policies undertaken in the countries studied and to underline the need for greater international coordination in areas like Europe and for better justified HSR policies. The calculations presented in this article use data relating to the urban populations which live in the vicinity of the world’s HSR stations, the distance from each of these stations to the nearest urban centres and the level of the corresponding regional GDP. All of this information has been used to build a GIS to facilitate analysis and pave the way towards a general comparative approach in which stations would be classified according to their capacity to attract travellers. Such an approach could also be used in areas in which lines are currently under construction and/or where future projects – such as the TEN-T in Europe – have already been approved but not yet executed. Our approach will make it easier to obtain data to show the potential success of, and need for, a HSR connexion as a preliminary step within the decision making process. This constitutes a significant contribution to the debate about the need to assess political decisions concerning HSR investments. It also highlights the need to encourage improved intermodality around railway stations and particularly around those located in non-metropolitan areas.
