This paper presents the field experience with a new kind of GPS based train control system for branch lines which are operated by radio-based operational train control. Most branch lines with such operating limitation cannot afford the cost investment for modern signalling systems. The train control system presented herein is a low cost solution which improves safety, makes operation easier, and introduces an interesting level of automation without costly line-side installations. It is based on autonomous determination of train location using differential GPS and an odometer with data radio communication between the central computer and the on-board computer in the train. In Austria, this system has been in full operation since 2006 on several single-track lines with a total length of approx. 90km. This paper will therefore present the experience with this GPS based train control system and its safety aspects.
