While some of the Melbourne trains can do regenerative braking, I have been told the rectifer stations cannot handle this so it is not used in Melbourne. The problem apparently is not enough funds availible for power supply upgrade, inspite of there being projected excellent savings can be acheived.
About a year ago I attended a lecture by an EE who works on the train system. He described in detail how they do regenerative braking and use super- capacitors to store the energy. Lack of money is a problem. Too much is being wasted on stupid things like FTTN which is turning out to be much more expensive than the original FTTP plan. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
