Every long distance train in China, Mongolia and Russia has a hot water dispenser in each carriage. Only the train from Hong Kong to Beijing has a sign which says, "caution, scald bums"! This photo from a November 2014 trip from Beijing to Hong Kong on the overnight T97 service.
This must be one of the most iconic symbols of Moscow and is St Basil's Cathedral on Red Square. The official name is 'Cathedral of the Intercession of the Blessed Virgin on the Moat' - a bit of a mouthful. The colourful domes represent flames rising into the sky. It is no longer a cathedral but a museum. Be sure to visit on your trip to Moscow.
