With the demise of K-Line some parts either have or will be soon non-existent. Currently Brasseurs has some inventory, some very limited others not so much . A member of SD3Railers has acquired a couple pair of K-Line E-8 AA's and the traction tires are pretty well stretched out but ok for a very limited time.
Does anyone know if any of the other brands are compatible, especially MTH since their diesels are one size fits all.
