Excellent perspective!

@Maersk.146 Thank you! The Cologne-Frankfurt high-speed railway has very good perspectives

Nice perspective.
It looks like a rollercoaster.

@ervanofoto Cologne-Frankfurt HSL indeed is similar to high-speed rollercoaster: The railway was designed to mountainous terrain with very extreme parameters of alignment: Design speed 300 km/h, maximum gradient 40‰, maximum cant 170 mm, minimum radius 3350 m.
