Manchester Metrolink Derailment

One incident in the city centre and the Eccles service goes bus only!
- Why - when the Alty services were being turned at Central?

Surely the Eccles service could have run from Cornbrook - or were
there only one or two sets left west of the incident and these got
allocated to the Alty service for convenience?

The system is far from incident "proof" and it shows

Perhaps there were 300 people on it and it derailed as a consequence of
being overloaded. ;-)

Many a true word spoken (written) in jest.

Isn't there some sort of rule about the centre of gravity of a vehicle
being affected by overloading?

I recall DB slapping draconian speed restrictions on trains in 1989
when the Iron Curtain came down, because of serious overcrowding. I'm
sure I remember reading that the centre of gravity played a role in
this.

Perhaps it was too many boisterous kids partying on the overladen tram
which derailed it?

The pictures seem to suggest that something prevented the
articulation from reverting to straight after the sharp
curve. Could overloading cause this?
