In 2005, the ITG was approached by Beaver Power Ltd, who wanted to buy the three locomotives for re-use in Sri Lanka. After much deliberation, the ITG sold Nos. 2 and 3 to Beaver for export to Sri Lanka, and moved to Merthyr Tydfil for overhaul and regauging to allow them to run on the 5&nbsp;ft 6&nbsp;in broad gauge tracks in Sri Lanka.<ref name="ITG1" /> Locomotive No. 1 was also sent to Merthyr Tydfil for parts recovery to enable the other two to be rebuilt to running condition. At the time, No. 1 was still owned by the ITG, and was not offered for sale until five years later.

In May 2006, Nos. 2 and 3 departed for Sri Lanka to work at a Holcim cement plant in the Puttalam area. The work included regauging to 5&nbsp;ft 6&nbsp;in (1676&nbsp;mm), fitting of a Rolls-Royce CV12 750&nbsp;hp Diesel engine coupled to a Twin Disc 13800 MS230 torque converter (both engines had lost their Diesel engines, torque converter and final drives in 1991), and repainting in Holcim livery.

In November 2010, the decision was made by the ITG to sell the stripped remains of No. 1 to Beaver, the sale being concluded on 28 November. This locomotive had lost its engine, torque converter and final drive in 1989, and was heavily stripped due to its use by Beaver as a spare parts unit. It is understood that the locomotive will be rebuilt for industrial service, whether in the UK or overseas.<ref name="ITG1" />

It is understood that, as of 2010, locomotive No. 3 has been withdrawn and heavily stripped for parts. The locomotive still carries the white Holcim livery that it was painted in when first exported to Sri Lanka, while No. 2 was repainted into a blue and white livery: it is still in service. No. 2 has been named, "Shakhti", and No. 3, "Prince Vijaya" - nameplates adorn the cabsides of each locomotive.  No. 2 has received a further repaint and now sports a red and white livery with yellow band.
