You are absolutely right,though we are not experts in Railways but it is understood that we should have little knowledge about Railways before commenting. Especially,if some one is abusing other member(especially if abusing someone's father/relatives) is UNACCEPTABLE in no CIRCUMSTANCES,No matter what other members/admins are commenting on your blog.I request Admin/Moderator to take a firm action against anyone abusing so that a repeat doesn't happen again at IRI
