NEW YORK, April 30 (Reuters) - Proxy advisory firm

Institutional Shareholder Services (ISS) on

Tuesday recommended Norkolk Southern investors elect

five director candidates proposed by activist investor Ancora

Holdings.

"We find that questions about the management and direction

of the company would be best answered by a reconfigured board

with more extensive and balanced industry expertise and the

benefit of access to all available information," ISS said in a

report seen by Reuters.

Ancora is seeking to replace seven board members including

Norfolk Southern ( NSC ) CEO Alan Shaw.
