Yes of course, here is the evidence...

A CFL Loco from Luxemburg pulls two international ferry Transwagons awaiting clear tracks to move to Luebeck freight yards.
All two hours running freight trains between Maschen Marshalling Yard (europe's biggest marshalling yard) to Lübeck freight yards.
Sometimes private or other state RR Companies getting these high payed orders, when reserve locos of the german state RR of the DB AG were not available.
The shortest possible train length is the loco only. Onto its back tour the loco pulls lot of freight cars coming from scandinavia via migration bird route by ferry from denmark across the baltic sea.
