Zangaon, aler, bhongir in each station goods trains are hauled in mainline. Everyday this is the situation repeatedly. After gowthami left the platforms they wont allow the goods trains to vacate the mainline. As in effect the trains which are running behind gowthami has to enter into the looplines and should reduce their speed and then has to come to mainlines. This will cause the delaying and increasing travelling time. The goods can be allowed in other timings rather than express timings if they are not that much important.
