EPFL Supercargo - The Project titled Clip-Air consists of a large sized normal aircraft and three capsule units capable of being driven on railways. Said capsules to be attached on the underside of the wings are possibly used for cargo transport as well as carriage of passengers, since they can be driven on train rails as well. This project allowing for people to get on a train and then fly without making any transfer, and at the point of arrival, continue traveling once again on a train, could possibly be used with varying numbers of capsules.

It is further expressed that the plane possibly operated with different types of fuels, would be carrying 450 passengers inside three capsule units.
