There is nothing called ER/NCR/ECR/NR when its about EDFC or other DFC!!
CTC got the task to address bottlenecks by centralising control at busiest nodal points & will work on same control mechanism as active at Control Room but with broader span!!
Every Zone is bifurcated in Section which is controlled by Section Controllers while EDFC will have several merge points with exisiting rail network. Control till Zonal Merge points of existing Rail Network will be controlled by Section Controller while CTC gonna handle remote signalling, real time train clearance instead of Section...
more... Block adherence. Further line capacity will increase as there will be none but CTC to track traffic flow!!
Further different screen will display every section whose centralised control will diminish slow paper work!!
