Railtrack was put into administration last October in a move that shocked the City and other stakeholders. Bondholders, including those who compiled today's message to Byers, lent Railtrack £1.5bn. They have effectively been forced to sign a special agreement with the Government, waiving their rights in exchange for continuing to be paid interest on their bonds. Now they are fighting back and demanding that whoever takes over Railtrack should offer bondholders the option of redeeming their bonds at par or at the appropriate gilt plus the appropriate spread, whichever is higher.
