The only problematic route here is goramghat-kamlighat in this section which can't be disturbed and where forest department is objecting.
So railways did a survey of a new line from phulad to kamli ghat (by avoiding heritage line of goramghat-kamlighat section). That's why its taking so long for this project.
i don't know where have u heard devgarh madriya-bar rumor?? I never heard of this before.
