What train routes are or are not included?
Long-distance Amtrak and VIA Rail trains are included on this map. For the purpose of this map, this is considered all Amtrak routes outside of the Northeast Regional that take longer than 12 hours, and all VIA Rail routes outside of the Quebec City–Windsor Corridor corridor. The excluded routes are shown with a grey line on the map for reference.
How are sunrise, sunset, and twilight calculated?
Sunrise, Sunset, and twilight are calculated using General Solar Position Calculation formulas from the NOAA Global Monitoring Division. Fully blue indicates the sun is 18° below the horizon, while fully red indicates ~0.833° above.
How accurate is it?
Terrain, weather, and train delays will all affect how much the scenery is visible along the tracks. As the data used to calculate train positions only includes station arrival and departure times, so to calculate when a train is at any given point on the tracks, it's assumed the train travels at a constant speed between stations.
