My Circle Trip was a bit longer. ;-)
I took the Capital Limited from DC to Chicago, the Empire Builder to Seattle, flew to Southeast Asia, took the Eksectif car on the train from Surabaya to Jakarta, flew to Singapore, took the night train to KL and stayed a day at the old Raj style hotel at the original train station which was pretty cool. Then I took a couple night trains to get to Bangkok where I stayed for a couple months. Then I got the train from Bangkok to Klong Luk and Cambodia, where things got a bit tragic. Cambodia was just a horribly damaged country and people. Beautiful, but it is painful at times to travel there. Took boats, trucks, taxis and a short train ride while I was there, then spent a month in Vietnam, taking the train from Saigon/Ho Chi Minh City to Hanoi, which was a trip to remember. I got "adopted" by a bunch of Vietnamese police officers who thought I was a drug runner at first but when I showed them my Real Estate business cards they insisted on inviting me to drink vodka with them. Never drink vodka with a Vietnamese person or a Russian. Just don't.
I started to recover from the hangover after we got to Hanoi, then I got pinkeye and moped in my room for nearly a week. From there it was a night train to Kunming in China, which is a BEAUTIFUL city. Then rode a train to Beijing, stopping off along the way a time or two. If they do the early morning aerobics on your night train, it is kind of fun to join in. They will laugh at you, but it gets the blood going. And definitely participate in the "What kind of tea are you brewing?" discussions/demonstrations at the samovar. Mandarin or Min not required but helpful to have. Beijing was just a blast, dirty air and ubiquitous construction cranes notwithstanding. Great Wall and Ping Yao are great overnight/three day excursions.
The big event was the Trans-Mongolian from Beijing to Moscow. That was simply unbelievable! Too long to digest in one go, but definitely a must do! Seeing Lake Baikal in the distance alone was worth it. And the Moscow Metro stations are a museum piece in their own right. Just amazing.
Then the end of the trip happened too fast. Red Arrow to St. Pete, seeing the cruiser Aurora during a snow storm, a mixture of trains to Kiev, Warsaw, Berlin, with a quick side trip to Krakow thrown in because it is a favorite. Then I think it was an IC to the Chunnel and on to London. I spent a week in the UK then took another train from London to Lands End. Passing Dawlish at high tide is too cool, check the tide tables and try to get there for it. The waves break over the sea wall and hit the side of the train, which is kind of entertaining.
Then it was Heathrow to New York and take the Regional from Penn to DC Union Station and home. The next day I was in the car taking clients to see a house, which was a kind of let down...
