Geoglyph Rail is an online train simulator with over 300 train lines and more than 100 countries’ railways. The data for each train trip is written in CZML.
Users can visit any point in the trip’s timeline and can regulate its speed. They can also view the landscape and train from anywhere they want, and they can easily take photos (screen captures) of the journey.
In the future, the app’s developers plan to run a railway in the virtual city using Cesium’s 3D Tiles.
