End of the line
Because it was so cold, Tracey and I decided to stay on the U2 to the end of the line at U Ruhleben. For much of the trip the train was packed, except may were obviously going to Olympia Stadion as once we left that station we were the only people in these two carriages 🙂
By the way – for the history buffs, Ruhleben was the site of a famous WWI internment camp ( http://bit.ly/1lQFUDF )
