The Sobu Line railway bridge is built far above the pedestrian crossing

Pedestrian crossing in front of Akihabara Station

If you leave Akihabara station and head towards Manseibashi Bridge, you will soon reach a large street. If you look over the pedestrian crossing in front of you, you will see an old railroad bridge over which the Sobu Line runs. Upon closer inspection, you will notice that the Sobu Line bridge in front of Akihabara Station is built quite high. It looks like a building was used as a bridge girder to build the railroad bridge.

The reason why this steel bridge is so high is that the Tohoku Main Line, which crosses the Sobu Line at Akihabara Station, was not only laid down first, but also elevated. Originally, the tracks were laid on the ground, but local residents protested that the tracks would divide east-west traffic, so the Sobu Line was extended to the elevated section in 1928, resulting in the current elevated line running on top of the elevated line.

It was inevitable that the elevated Sobu Line, which was built to straddle the elevated Tohoku Main Line, would be even higher. Even if the Tohoku Main Line had not been elevated, it would have been difficult to construct a track that dropped sharply (or rose sharply in the opposite direction), considering that Ochanomizu, the station next to Akihabara on the Sobu Line, is located on a plateau called Surugadai.
