Typically the track network data model is maintained as an afterthought or with primitive tools or complex procedures. A software tool set to manage unified set functions needed to manage a track network is a sizable, complex and costly endeavor and thus difficult to justify. Bentley Systems, a developer of engineering systems software, has had the opportunity of combining work in the highway a...

The purpose of the thesis was to further investigate the possibility to complement the rotary converters with a phase shifting device as a continuation of the work done in the master thesis; Load flow control and optimization of Banverkets 132 kV 16 2/3 Hz high voltage grid. With this modification, rotating converters can be used almost as flexible as static converters. The earlier thesis has c...

The railway system is vulnerable to disruptions that require careful management of available infrastructure capacity in order to keep operations feasible and attractive for passengers and for the environment. Dispatchers manage traffic with a limited view on the network impact of their actions. Effective large scale dispatching solutions are required to better forecast the delay propagation in ...

In this project we give a special idea of anti-collision in train. In this project we demonstrate the idea of track crack checker and this information send to CAN (control area network) and display all condition and respective zone of track. And this information send to train that comes on same track and train automatically stops. other feature of my project railway track gate control automatic...

The shield tunnel of the Kunming subway crosses beneath the Kun-Shi Railway. Due to the high requirements of railway track for settlement control, this article proposes the following technical measures for controlling the settlement based on the analysis of risks arising from the shield crossing railway: (1) Reinforcing the stratum of the region crossed by the shield in advance to achieve high ...

Global Navigation Satellite Systems (GNSS) are applicable to deliver train locations in real time. This train localization function should comply with railway functional safety standards; thus, the GNSS performance needs to be evaluated in consistent with railway EN 50126 standard [Reliability, Availability, Maintainability, and Safety (RAMS)]. This paper demonstrates the performance of the GNS...
