Its easy. Create a graph. The vertex set V is a set of all stations. If there is a direct path between two station in any bus path then place an edge between those two stations in the graph and set the label of the edge be the set of bus lines that have that path. Starting from the Start run BFS until you reach to the End. The number of possible solutions is the the multiplication of the size of all sets on the shortest path.
