Network Rail is to issue a benchmark sterling index-linked bond due November 2037 in the week of April 30 , the national railways operator said on Wednesday (25/04/2007) , signalling the first bond under a new programme of inflation-linked issues (link below.)

Network Rail said the programme would comprise two or three large issues with maturities of between 15 and 45 years. The bonds will be directly and unconditionally guaranteed by a financial indemnity from the UK government , it said.

"We expect to raise a total of 10 billion pounds in the capital markets over the next two years to finance new investment in the railway and to refinance our short-term debt. Much of this could be index-linked if investor demand remains strong,"
