Wait till the new TT is released. It takes time to work out schedules, passages, timings at originating stations, intermediate stations, turnaround stations, and route stations, crossings from the other end. It's not as easy as just switching on your new tubelight in another area of the room, instead of the one you are used to. This is said to ILLUSTRATE the difficulty of re-routing trains. What about the person who has booked under the old system of 90/120 days who's going to ED, and suddenly finds that the train is NOT going to ED ? What should he do ? think, sir, Think. And take this post in the right spirit.
