Moving trains represent a voluminous mass of users moving at high velocities that require bandwidth (on demand). Existing solutions typically based on wireless technology alone cannot scale efficiently to provide for bandwidth to such fastmoving voluminous users. A new approach is proposed that facilitates dynamic provisioning, good scalability and efficient use of available bandwidth. The prop...

Typical passenger trains have specific weights between 400 and 800 kg per seat, but some high speed trains such as the German ICE 2 have values as high as 1100 kg/seat. Although there are some railway-specific limits to light-weight efforts, such as side wind stability, the Japanese Shinkansen (537 kg per seat) and the Copenhagen suburban trains (360kg per seat) may serve as benchmarks for ligh...

Automotive telematics has become an important technology for high-speed rail systems, which are being increasingly popular in this era of green technology. As the train speed increases, however, communications between the train and infrastructure encounter major difficulties of maintaining high quality communication. Handovers on high-speed trains occur more frequently and have shorter permissi...
