I think this is JR fastest limited express in Japan. Avg speed constant at 120-125Km/h. JR East & West & Shikoku & Hokkaido should learn from JR Kyushu....Limited Express should travel with this kind of speed not 100 - 110km/h
The fastest limited express on the conventional line is JR West's Thunderbird No. 37. The nominal speed exceeds 106 km. It seems that it is not effective in terms of cost effectiveness because it costs a lot of initial investment and maintenance cost to speed up the train.
Certainly it sounded like a ventilation fan or an air conditioner. This train takes 123 minutes at a distance of 198.5 km, so the average speed including the stop time is 98.6 km / h. The maximum speed is 130km / h. The only trains that are faster than this average speed are the Thunderbird, Dinostar, and Shinkansen, but all of them have a structure where you cannot see the front except for the driver's cab.

The high pitch sound you were referring to sounds like a ventilation fan. Also, you say this is the fastest observation car, how fast does it go?
