I read with interest the following article:

http://www.heraldsun.news.com.au/com...5E1702,00.html

This is the first I have heard that any passengers evacuating trains in
London during last month's terror attacks were electrocuted by a live rail.
Was that true? Sydney's system is powered by overhead wire, so that danger
doesn't exist in Sydney's tunnels.. Vince Graham continues to defend the
indefensible in continuing to maintain the policy of locking people in
trains without any passenger actuated door releases available, and the
absence of any devices to enable passengers to break or remove strengthened
glass windows in trains to escape.
