Controlling Rail Potential on Dc Supplied Rail Traction Systems
Most of the modern DC electrified mass transit systems use a totally floating earth as their grounding strategy. A well known problem related with totally floating systems is that the touch potentials can be dangerously high. In order to reduce the voltages on rails, several devices exist. Most of these devices allow a direct connection to earth when a certain voltage threshold is exceeded. In ...

متن کاملWeld defect formation in rail thermite welds
A previously developed heat transfer model is used to study the influence of welding parameters on weld defect development in thermite welds. Weld defect formation maps are constructed from a series of heat transfer simulations. For the current normal rail thermite welding conditions, it is found that shrinkage cavity formation can be avoided but cold-lap and centre-line defects are likely to o...
متن کاملShared Intermodal Terminals and the Potential for Improving the Efficiency of Rail-Rail Interchange
While largely due to conditions outside their control, the configuration and setting of current intermodal rail terminals contribute to congestion and increased freight handling volumes that have resulted in additional transportation costs for shippers and carriers. Although a substantial body of research has focused on improving the efficiency of port operations and multi-modal freight shipmen...
متن کاملon Minizing Mechanical Stresses of the Rail Way Wheels
The purpose of this paper is to study the behavior of elastic-plastic stresses under severe drag braking. A railway wheel performs three tasks, aiding in trian movement, supporting the car load, and acting as a brake drum. Finite element computer programs are developed for elasto-plastic stress analysis. An attempt is made here to find an improved fillet profile of the wheel with the intention ...
