Freight remain slow & Auto signal keep blinking yellow till Freight gets parked!! & yes, u keep safe distance maintained, while in normal mode, u can push rake till preceding Freight/Rake Tail!!
Nw load the same count @ Semaphore way...the train whch remain crawling blocked in between station in AUTO mode, will b blocked @ station for clearance!!
& imagine...station do hav limited capacity to hold Passenger/Freight Rakes...n u cnt block trains awaiting @ outer,,cz it gonna load other remote station n sooner u gonna find...huge blocked jam & movement hampered..cz u dnt...
more... hav any mode to keep load moving in between stations!!
