Routing Cars in Rail Freight Service • Railway freight transport has a market share of 20%. • 100,000 Mil. ton km, of which: 45% inland traffic, 45% cross-border traffic, 10% transit traffic. • Deutsche Bahn offers whole trains (~30 cars) and individual cars. • Several individual cars with different destinations are grouped to trains at classification yards. • At the next classification yard, the cars are re-grouped, until they reached their destinations. • Main question: what is the “best” path for each car?
