Train at high-speed - Almost an inertial frame of reference

Travelling at about 180 km/h through the Gotthard Base Tunnel. The coffee almost doesn't move.

The Gotthard Base Tunnel stretches 57 kilometres (35.4 miles) and plunges as deep as 2,450 meters (8,040 feet) below the mountains. This marvel of modern engineering revolutionizes travel through Europe. Yet, while travelling in the tunnel at high speed, it almost feels like being in an inertial reference frame.
