This from the "All Aboard" list:
A passenger aboard the Empire Builder, Train 7(26) reports no air
conditioning all day in four of the train's coaches; the cars have been hot
since St. Paul, where he boarded.
Outside temperatures were around 90°F
in North Dakota, dropping at night to the mid-70s.
A tour group to
Glacier Park, which had been booked on the train, was handled instead on nice,
cool, air conditioned buses. The regular passengers, however, have to ride in
the heat.
Apparently the train's engines are generating HEP, but the
coaches' air conditioning is broken.
This has been confirmed with another source. The train(s) continued
to operate through to destination (hoping the problem could be fixed?).
Trains 7 and 27 were showing as service interruptions because the space was
blacked out (didn't want to sell tickets on a hot train). No buses were
available at Havre, so some were given the option of staying overnight there (on
Amtrak's dime) until the next day's train.
