Next to the train schedule, there will be information about seat availability. It will show the number of available seats in different classes (e.g., Economy, Business, First Class). If seats are available, you will see options like “Available,” “Waitlist,” or “Not Available.” https://medium.com/@nishantindivedic/how-do-i-check-the-schedule-and-availability-for-my-route-15b28a9c8b91
