California Roadbed Co., Inc. is making some changes in the HO Scale, N Scale and O Scale product names. When a roadbed has two thicknesses in the same scale, the thicker will be called Main Line (ML) and the thinner will be called Branch Line/Siding (BLS). HO (0.240” thickness) is now HOML and HO125 (0.125” thickness) is now HOBLS. OHL (O Heavy line 0.350” thickness) is now OML and OSL (O Slim Line 0.250” thickness) is now OBLS.   | Ballast | N Scale Products | HO Scale Products | HOn3 Scale | S Scale Products | O Scale Products | LARGE SCALES | Sample Kits |   © Copyright 2005-2007 California Roadbed Co., Inc. all rights reserved CalRoadBed.com The Finest Model Railroad Roadbed on the Market info@calroadbed.com All Orders Are Secure!
