Ya required bro, trains are left at platforms itself after they reach station. In other words they are used like parking lanes.
In real scenario for handling trains and all not useful. They can shift cleaning and watering for some trains which go through bza to decongest but they won't do it. Only God knows why 8th platform is required. Most trains use PFS 1,4. 6th is used for trains going to bza like Golconda,DD when it used to run.7th was a small one and used for science express like trains.
