Locomotive G616 is one of a class of seven shunting locomotives constructed between 1961/62 by Motorenfabrik Deutz at Köln, Germany. The locomotives were specifically designed for shunting and light branch line work. Locomotive G616 entered traffic with CIE on 4th June 1962, and lasted in service until 2nd May 1977. The locomotive was officially withdrawn on 29th July 1977. 

Following withdrawal by CIE, this locomotive, along with sister locomotives G611, G613, G615 and G617, were sold to Comhlucht Siuicre Éireann (Irish Sugar Company). G616 was then used for shunting at the sugar factory at Carlow. Locomotive G616 was subsequently moved to the Thurles factory when rail-borne operations at the Carlow factory ceased. G616 was to remain at the Thurles factory until it was preserved, along with G617, by the now defunct Great Southern Railway Preservation Society (GSRPS) in the mid-1980s. Both G616 and G617 were then moved down to the GSRPS’s base at Mallow, where as start was made on their restoration.  

However, this project eventually floundered in 1990, and both locomotives were then sold to the Deutz Operators Group (DOG) in November 1990. The DOG was made up of four of the then Committee members of the ITG, who stepped in to purchase the locomotives to prevent them from being sold for scrap. At the time, the ITG were unable to take the two locomotives as the Group had not yet secured an operating base. Whilst they were at Mallow some restoration work was carried out on G616, however, as both locomotives were stored outside, and off their wheels, the scope of work that could be carried out was extremely limited. 

Once the ITG had secured its base at Carrick-On-Suir, ownership of both G616 and G617 was transferred to the ITG in August 1993. Both locomotives were re-united with their wheels, and were then moved by low-loader to Carrick-On-Suir. Once at Carrick-On-Suir, work commenced on stripping down G616. Over the next three years good progress was made on its restoration, with most of the frame and cab fittings being cleaned up and repainted. However, a lack of volunteers, coupled with other various commitments, meant that work on G616 eventually ground to a halt. 

G616 remains in a dismantled state inside the Goods Shed at Carrick-On-Suir awaiting volunteers to help complete the restoration work and reassemble the locomotive.
