This is an actual JR (Japan Railways) train ride (starts at 01:26) between HAYAKAWA station and ODAWARA station on the TOKAIDO line in KANAGAWA prefecture, just south of TOKYO.
The train ride itself is only two minutes, but the scenery outside the window changes quite a bit.
00:05 – Hayakawa station platform
00:56 – Train incoming
