Central Railway's prestigious Rajdhani express works with Push-Pull configuration. This 22221 Rajdhani express to Nizamudin has a similar WAP-7 locomotive at the other end. Both the locomotives work simultaneously and are controlled by crew in driving cab. With working locomotives at both ends, the train accelerates faster and does not need additional pushing locomotives while passing through Thull ghat section thus saving time of attaching and detaching such pushers.
