Casual registration is not possible in this case.
Example of a casual registration : When Mr A who has a cloth shop in Maharashtra goes and puts exhibition in the state of Assam. In this case casual registration shall be taken.
However, since your client shall be undertaking works contract of railway in various states which is his principal business, so casual registration wont be possible.
