Ultra-high frequency train operation for the realization of Ultra-Convenient Rail Transport (UCRT)

Abstract

Ultra-Convenient Rail Transport (UCRT) is the concept of a new railway system with the capability of revolutionising the convenience of the services offered by the rail transport. One of the important technical challenges in realizing UCRT is the drastic increase in train frequency, because UCRT has to meet the very wide variety of needs of the passengers. The authors discuss that the combination of moving block signalling, synchronization control of the group of trains and other more advanced techniques, such as on-board switching, under which the train can decide the route it is going to proceed at a junction unlike conventional railway systems in which trackside turnout devices will decide the route, will help bring the ultra-high frequency operation closer to reality. In this paper, the concept of UCRT is first explained in detail. Following this, the technical possibility of high-frequency operation using the combination of above techniques, and the challenges that need to be addressed such as the further shortening of the safety distance under the moving block signaling system, are discussed.
