According to the Alaska Railroad timetable, Hurrican Bridge is Mile 284.2 and Anchorage is mile 114.3, a distance of 169.9 miles. At 35 mph, the train will take 4 hours 51 minutes 15 seconds.
7 knots is equal to 12.98 km/h , so the effective forward speed of the plane is 187.02 km/h. In the amount of time shown above, the plane would travel 907.9 kilometers. Depending on which airport in Dallas the plane left from, it would be near one of the small towns a short distance West or Northwest of Lincoln Nebraska (I'll say Raymond, Nebraska) at the same time the train reached the Hurricane Bridge in Alaska.
