Sept 24 (Reuters) - Norfolk Southern ( NSC ) said on

Tuesday it has appointed Jason Zampi as its chief financial

officer, replacing Mark George, who was promoted to the position

of the railroad operator's top executive recently.

Norfolk Southern ( NSC ) let go of CEO Alan Shaw earlier this

month, following an internal probe into allegations of ethics

policy violations and picked George to lead the company.

Zampi has been with Norfolk Southern ( NSC ) for 13 years and has

prior experience working at accounting firm KPMG.

The appointment comes at a time when Norfolk's board has

been tackling one crisis after another including former CEO

Shaw's ouster.

Norfolk was also involved in a boardroom battle with

Ancora Holdings which culminated with the activist investor

winning three board seats and last year's train derailment in

East Palestine, Ohio.

The company has also been navigating labor deals at a

time when thousands of employees in the industry are negotiating

for better pay and working conditions.

In August, Norfolk reached agreements with nine of 13

unions that represent its workers, covering about 55% of its

unionized employees.

Shares of the company fell about 1% in after market

trading.
