ye rule hi galat hai... jbki aisa hona chahiye ki .. jo zyada late hai usko zyada priority milni chahiye..
for e.g. one train is 2 hrs late .. still a train which is 20-30 min early will ot it .. better to run it non stop on long streches to cover its delay .. this will be helpful for all people .. aplying this will make most of train punctual ..
