CSE didn't hire the G-class, they purchased them. G613 at Tuam, G611, 615, 616, and 617 at Thurles. G611 was later 'lent' to CIE to shunt the wagon works at Limerick but this local arrangement caused ructions when news reached the the powers that be at Inchicore. The Rustons held sway at Carlow and Mallow CSE factories.
