Indian Railways generally prepare reservation charts around 4 hours before the scheduled departure time of the train. However, please note that this information may have changed since then, and it’s always recommended to refer to the official Indian Railways website or contact their customer support for the most up-to-date information.

To view charts online, you can follow these steps:

1. Visit the official Indian Railways website, which is www.irctc.co.in.
2. Log in to your account using your username and password. If you don’t have an account, you can create one by clicking on the “Register” option.
3. Once you’re logged in, click on the “Booked Ticket History” section. It is usually located on the left-hand side of the webpage.
4. You will see a list of your booked tickets. Find the ticket for which you want to view the chart and click on the “Get Train Chart” option next to it.
5. The chart will be displayed, which will include details like your coach number, seat number, and other passenger-related information.

Please note that this process may vary or change over time, and it’s recommended to refer to the official Indian Railways website or contact their customer support for the most accurate and up-to-date information on viewing charts online.
