Application Condition and Operation Procedure of Motor Train Unit Multi-Connection within Passenger Dedicated Lines

Based on the features of Motor Train Unit (MTU) multi-connection, this paper focused on the shortage section of carrying capacity and analyzed the application condition and operation procedure on passenger dedicated lines (PDL). The results indicated that the extra running time, due to the parallel routes detour, played an important role on multi-connection and detaching. If the running time is less than multi- connection time, the parallel route detour can be considered as the scheme; if the running time is more than the sum of multi-connection and detaching time, the multi-connection operation (disconnected) can be regarded as the good one; if the running time lies in between, the multi-connection operation (un-disconnected) is the good one. The analysis on operation procedure showed that it can be realized technically by multi-connection or detaching for MTU during the application.
