Terrorist bombing taken into consideration in new carriage design by Newcastle University. www.bbc.co.uk/news/uk-england-tyne-21159423Includes video footage of retired Metro carriage being demolished by an explosion, showing the various failure modes. Fantastic piece of work! |

Where did that decomissioned carriage come from? It has many characteristics of a Japanese train!

I don't get this. Why would you want to contain the blast within the carriage. Wasn't that the reason the Piccadilly Line train on July 7th suffered more damage and casualties than the other two because it was contained within the tunnel?
If the blast has nowhere to go, then surely it will reverberate around inside whatever is holding it. Granted the modified carriage has break away safety glass and whatnot, but still.

I noticed the doors went very quickly, so anyone near the doors would be blown out of the vehicle. Seeing as many passengers congregate near the doors it seems possible that the casualties will be increased not reduced.

I saw a item re this on SKY news today.... Watching the report, certain items (e.g. one or two doors and specific windows) dislodge intentionally so that internal pressure is dissipated, whilst the ceiling and internal items are dislodged as little as possible, reducing injuries inside a car as much as possible. On the old Japanese/Madrid [?] vehicle, windows and doors traveled in every direction... whilst the white test vehicle clearly dissipating pressure in the safest way, therefore reducing the number of objects flying from or within a car... so this would seem to be way forward to me. |

One of the stated objectives was to stop the gangways getting blocked by falling debris. Can you imagine all the grab rails in the current design of tube stock being thrown across the aisles? Getting through there to help people or get someone out would be like being a ball in a game of Kerplunk. Another stated objective was to minimize collateral injury when the car was outside of a tunnel, which most of the network is, if the truth be told.
