A rather lonely journey through Berlin at night. The last train of the S46 line to Grünau. Often referred to as the rag-and-bone train, it gives those who have spent the night in pubs and other establishments one last chance to get home. At 1:00 a.m., the ‘platform are raised’. The S-Bahn stops running until around 4:00 a.m. Meet the last trains on the ring, all heading for their depot. Bring the train safely to Grünau and park it there.
