Stray current causes inevitable corrosion to structures near electric transportation systems, especially in DC urban rail transit. The paper considers the issue of stray current mitigation discussing what can be done for design and existing systems, sticking to applicable standards and consolidated protection practice. Mitigation measures may be de...

... and high insulation of fourth rail, the stray current issue of DC traction system may be solved fundamentally. But the fourth rail system requires the train modification and high cost; it's only applied in a few lines, such as London Underground, Milan Metro Line 1, etc. The configuration of DC booster circuit traction power system is shown as Fig. 20. Compared with the third rail configuration, DC booster system adds multiple DC boosters and specific return cable [26][27] ...

Corrugation of railways is well known to occur at large longitudinal or lateral creepage, i.e. in regions of large acceleration, braking or tigth curves. The vast majority of present models considers creepage to be however such that traction ratio is smaller than the limit one given by friction coefficient. Further, generally friction coefficient i...
With the rapid development of the economy, the existing conventional bus transit system finds it difficult to meet people’s increasing travel needs. In addition, with the emergence and rapid de-velopment of urban rail transit, it is also necessary to integrate the existing conventional bus transit system with the rail transit system to realize the...
Passenger exchange coefficient is a significant factor which has great impact on the pricing model of urban rail transit. This paper introduces passenger exchange coefficient into a bi-level programming model with time differential pricing for urban rail transit by analysing variation regularity of passenger flow characteristics. Meanwhile, exchang...
One of the environmental challenges in the urban rail transportation industry is the vibrations and noise caused by the railway passage. Vibration prediction methods are divided into analytical, quasi-experimental, and numerical modelling methods. Factors such as higher train speed, rail joints, crossovers, wheel flats or rail corrugation, low soil...

The focus of this Master Project is on ground-borne vibrations caused by rail transit that operates in urban environments, i.e., a class of relatively lightweight and slow-moving trains that frequently run close to buildings and facilities. Specifically, the work commences with a review of existing knowledge about rail-induced ground vibrations: (i...
