- My name is Jeff Smith and am the owner of Branchline Products. For the past 32 years I have been trying to promote 1.5" scale running on 4-3/4" track. We have a small but very enthusiastic group modeling mainly D&RGW narrow gauge. Most of my customers are 1.5" standard gaugers using my detail parts on their early era equipment.
Branchline Products has published their drawings for DRGW narrow gauge trucks.
