Train scheduling is one of the significant issues in the railway industry in recent years since it has an important role in efficacy of railway infrastructure. In this paper, the timetabling problem of a multiple tracked railway network is discussed. More specifically, a general model is presented here in which a set of operational and safety requirements is considered. The model handles the tr...

Trains are running through a rail network trying to meet a predened schedule, the Ocial Timetable, which species when each train enters and exists the stations on its route. When one or more trains deviate from the ocial timetable, new schedules and possibly new routes must be identied and implemented very quickly. Also, the new plan should minimize some measure of the delays. In a rst and very...

Conventional approaches to measuring accessibility benefits are not capable of fully measuring the total accessibility benefits of integrated land-use ^ transport strategies, in which both land-use and transport changes form part of the policy strategy. In this paper a comprehensive methodology for analysing accessibility impacts and accessibility benefits, which is based on location-based and ...

This article describes a search algorithm adapted to the Spanish Railway Network for generating as many traveling options as possible between two railway stations. This algorithm (Warshall’s algorithm) uses connecting matrices to find all possible railway journeys. The Spanish Railway Company has imposed severe restrictions: less than 1 second per query in a 600Mhz processor PC with 32Mb RAM an...

The paper presents data on the occurrence and secondary spreading of rare and threatened vascular plant species in railway habitats of Slovakia. We recorded 17 threatened vascular plant species and other 9 species that we considered to be rare in Slovakia. They grew at railway stations, mainly directly in the rail yard and also at the platforms or other similar facilities. Records of further 39...

Locating events in Southern California is quite simple since we have about 500 stations, with a large fraction broadband (TriNet). We locate and identify within minutes. Thus, we have an opportunity to test hybrid methods against the full array estimate. Here we report on three projects addressing these issues; (1) locating events using one calibrated station with waveform data plus a few other...

Guinea-worm infestation is prevalent in some sections of the Hubli Medical District of the Southern Railway. These sections are situated *n the civil districts of Dharwar, Bijapur and ^holapur of Bombay State. No cases are encountered among residents of railway colonies as no step wells are in use, but railway employees, especially engineering gangmen, who *jve in the villages adjoining railway...

Study on search algorithm of passenger travel route in railway transport network is of great importance in evaluation on railway operation benefit. Based on features of large-scale network and railway passenger transportation organization, the paper firstly innovatively puts forward the generation method of alternative route set in multiple constraint conditions. K short routes is proposed base...
