There are actually 3 working platforms at PTA. I don't whether the 4th one which is 1A can be considered as platform or not because the only train which is 54558 departs from PTA from PF 1A which is actually not opened from both sides. 54558 is also placed sometimes on PF 3 as well. Now I am not sure whether this can be considered as PF or not. UMB also has 7 PFs plus 1A pf. but no. of PFs has been written as 7 on this forum.
