Principles of Railway Location and Design

Principles of Railway Location and Design examines classification and classing methods of railway networks and expresses theories and methods of railway route selection and design. Railway networks represent modal transfer, which significantly alleviates traffic congestion and pollution The book introduces capacity enhancing methods for existing railways and implementation plans and technical conditions for improving existing passenger railways, building new high speed railways and developing heavy haul railways.
