Bullet train passing through Koriyama station - jump to

Super fast Bullet Train (known as The Shinkansen/新幹線) speeding through Koriyama station, Fukushima prefecture.
This video shows two Shinkasen coupled together. The green train at the front is an E5 series Hayabusa/Hayate which is joined to a red Komachi E6 series train.
This train was heading south towards Tokyo, probably originating in Akita. We estimated its speed to be around 160km/100mph as it passed through the station. How fast do you think it was going?
