How does H1 differ from other AC classes? First Class AC, marked as H1, stands out from other coaches in several ways. It features private cabins instead of side seats, has a separate entrance, and includes sliding doors. Each cabin typically has two seats.
What about H2? If your ticket shows "H2," this also indicates First Class AC. The First Class AC compartment is divided into two sections: H1 and H2. So, if H2 is on your ticket, your seat will be in the H2 section of the First AC coach.
