vskp HAS 8 PF, but its all poor management. As other blogger said there is no blockage if train leaves from PF1. In only one criteria out of 5-6 where train blocks all when leave from PF1 and goes towards MAS side. Its just mismanagement.
This PF blockage can be every where, even at BZA of train come from chennai to PF1 and goes toward Warangal and also at chennai if train starts from pf1 and goes towards Arakkonam.
