Safety boost for new Metro lines

FUTURE Metro lines in Shanghai will have additional protection against flooding and terrorist attacks as stronger, more efficient defense barriers are to be installed inside tunnels.

These gates could be quickly closed to protect trains from flood waters, toxic gas or explosion waves.

An older-generation product is already installed inside some tunnels in the city's current 12 Metro routes.

The under-construction extension to Line 11, Metro Line 12 and 13 will have the new defense gates installed inside their tunnels, according to local Metro management.

Orders have been placed with Shanghai Dikong Corrosion Prevention Equipment Co Ltd.

"Tests have proven the new product could successfully keep out water and gas. It has been put into production for installation on the new Metro services," a company official.

In addition, drivers are also able to manually close the gates to protect trains if required, the company official explained.

The new design has integrated the anti-flood and anti-attack functions currently performed by separate sets of gates inside existing Metro tunnels.

The combination will help reduce construction costs and raise protection efficiency, according to the product designer.

The use of a different type of concrete in the new gates means they will also be stronger and more resistant to damp, the producer said.

Metro management said, unless necessary, the older defense gates on current Metro tunnels would not be replaced by the new product.
