This train, the Marti Express Shuttle is a rarity. It was designed to work exactly like a lorry, but on rails. It can take two containers as a load and it can additionally haul a rake of unmotorised wagons, so that the full loaded train can carry 18 containers at a time, without the need of a locomotive and with the speed of 120 km/h. It was thought to be a good idea, but it really never took off. First there was a plan to use several of these trains to haul containers over the Alps between Germany and Italy, but for that purpose the engine was too weak. The bernese construction company Marti bought the prototype train and has used it with specially made gravel containers for moving large amounts of sand or gravel to construction sites or away from them. But for even this purpose the one small lorry engine has not been enough, and therefore this train has often been seen with an old SBB electric locomotive at its other end. That operation mode has the benefit that there is no need to turn the train around, it can run in both directions.

The Marti Express Shuttle seen from the other direction in front of a pile of normal containers. Behind the cockpit a heap of yellow, lower containers can be seen. These are the specially made gravel containers. These have also been used at construction sites where for example a tunnel is being bored through a mountain and huge amounts of broken stone needs to be transported away.
