Tomball locomotive works was Jason Smith, aka superturbine here on railwire. he made many cast resin shells for modified Kato chassis of the mikado, and GS4 mechs. Life, kids and motorcycles got in the way. His layout featured in N Scale Railroading MAR/April 2010 is still standing, hoping as life slows down a bit he may get back to some casting work, were are keeping our fingers crossed!!!!!
