Q: My friend and I left our hotel early, about 6:30. The walk took about fifteen minutes to the station. We had to walk down a long flight of stairs down to the station. We took out our automatic payment cards, walked up to the barrier, and swiped them across the electronic reader. The barrier opened to let us in. We walked up to the map that shows how the different train lines run. We confirmed that we would have to change trains halfway there. We looked at the signs to locate the platform we needed, and walked down another flight of steps to catch our train. We waited on the platform at a safe distance until the train came roaring in. After it came to a stop and the other passengers got off, we entered the train. It was mostly empty and we were able to find seats. At the third stop we got off and quickly walked up another flight of steps to locate the platform for the next train. In two minutes our next train arrived and we got on. This train was crowded and we had to stand. Four stops later we arrived at our destination. We left the train and walked towards the exit.  We passed another set of barriers and swiped our cards again, and then took an escalator up out of the underground to the street.

Did they sit or stand while traveling?
