As of June 2013, the Spanish AVE system is the longest HSR network in Europe with 3,100 km and the second in the world, after China's. On the line from Madrid to Seville, the service guarantees arrival within five minutes of the advertised time, and offers a full refund if the train is delayed further, although only 0.16% of trains have been so. On other AVE lines, this punctuality promise is more lax .
