Here's RSSX 1051 in a line of locomotives in North Little Rock, Arkansas on June 21. To me it appears it's been recently repainted. Looking at the RSSX roster, it's a GP10, now assigned to Huntsman in Port Neches, Texas. It used to be IC 9106, ICG 8106 and MSRC (Mid South Locomotive) 1057. According to Tom Balzen: "Hadn't seen anything like that before.  I Googled Locomotive LEAF and got the following result: http://www.railserveinc.com/leaf.html#locomotives

"This is a single GenSet locomotive featuring a Detroit Diesel DX370M, 550 HP Genset.  Good for low speeds and switching.According to Railserve's website, they have converted 15 former "hybrid" type locomotives into these and six "conventional" locomotives into these.  All are in use at various Railserve contract switching sites.  The website shows a photo of an EMD switcher conversion. LEAF (look on the long hood of RSSX 1051) stands for "LOW EMISSIONS AND FUEL". There you have it.- Tom Balzen"
