Railway Forum - Bridge collapse on Mexico City Metro

G'day BW,
Yep, I did espy this tragedy on the international tv news here.
Getting squished by a train from above would be an unexpected dilemma.
One now wonders about the structural stability of all elevated railways.
Rust and corrosion being a potential drama.
The elevated railway that intrigues me is the dangler in Wuppertal Germany.
I have squizzed a photo of one of the two car trains derailing and plunging into the Wupper river below.
Plus, a tragic animal incident when an elephant (forget the name) went berserk inside a train during a promotion stunt.
It smashed out the door and tumbled into the river below.
Steve.
