This paper describes an algorithm that determines routes using three graphs: the railway graph, the train timetable graph and the summary timetable graph. The search in the timetable graphs is guided by a subgraph of the railway graph, which is defined by the nodes that form an ellipse around the minimum distance path from departure to arrival. We also present some performance evaluations of our proposed algorithm. Finally we describe an extension of this algorithm that can be used in conjunction with block agents to find routes in large timetable graphs, and some applications for medical domain.
