In order to find the number of general compartments available in a train you can go to India Rail Info .
- In the search column type the name or number of the train and hover the mouse pointer to time table in the drop down menu which appears when you place the mouse over the train name.
- Once you are on the timings page, find Rake/Coach Composition (Which is normally at the top part of the page)
- In the Rake/Coach composition search for GS or UR ( GS in Indian Railway means General Second Class and UR means Unreserved, both denotes general compartment).
- Happy Journey : )
