LSLX/ Lone Star leasing Company

I have recently heard and seen this railroad. The plastics planty in Point Comfort that I drove by had a few of there engines. I have not been able to find a roster which has these engines in them. The engines in question are 903, 1710, 1675, and 1354. The first three are all in BN cascade green and the last is in ATSF freight warbonnet. The first is a SW unit where the rest are first generation EMD units. Any info will be helpful on the makes of these units.
