It appears that nowadays rail vehicles are not the primary choice of transportation for people going to the airport. The inconvenience of carrying luggage on railways deters passengers, who look for alternatives. Attempts have been made to encourage passengers to travel to the airport by rail. However, significant limitations in these existing systems suggest a need for extensive work and adjustments, but this would increase the price and discourage passengers. This study investigates the potential for implementing an on-board check-in and bag drop system onto rail vehicles. By observing the Tyne and Wear Metro, Newcastle, the UK the benefits and limitations of installing such a facility have been explored, by the development of suitable operations and interior designs. Four designs which meet the design criteria were produced and their limitations considered. This study concludes that the potential for an on-board check-in and bag drop facility is realistic. Each design brings key benefits and limitations, and all meet security, and health and safety criteria. A feature incorporated into all designs allows for the equipment to be removed easily and stored away, helping with a low cost and versatile approach.
