This gallery is a composite from a number of longer Amtrak journeys. It attempts to illustrate they are invariably multi-day excursions by having end and start of day in the middle. To show you can do this all year, the first half is winter scenes and the second from summer trips.
These photographs include scenes seen from the Amtrak trains the California Zephyr, the Coast Starlight and the Empire Builder.
There is an accompanying blog post in the Journal.
