Cement manufacturer Lafarge is on the final stages of its £7m investment programme at the Dunbar works.
The work will last until 2011 and will include work on the control system. The final investment of almost £500,000 includes two locomotives to replace three vintage inefficient engines in the rail bulk loading and distribution area.
A new £1.5m paper bag packaging plant was completed in September, a £3.5 million plastic bag packaging plant and extended warehouse in 2007.
The two new engines have been named ‘Doon Hill’ after the local Dark Age settlement at the bottom of the Lammermuir Hills opposite the cement works, and ‘Black Agnes’ after Lady Agnes Randolph who held off the Earl of Salisbury from taking Dunbar Castle during a five-month siege in 1338.
