Yesterday, we went on a day trip to #Oxford by #train. No other means of powered transport was used as we #cycled to and from our local #RailwayStation.

Here is the #countryside zooming past the train window.

Balls rolling under gravity on a cycloid and on straight lines inclined at various angles.
