Hartland Locomotive Works specializes in high-quality, affordable G-Scale Locomotives and Rolling Stock: coaches, freight cars and cabooses. We also manufacture brass and aluminum track and other accessories for the Garden Railroader. HLW equipment is designed to run on no. 1 gauge track and is compatible with other G-Scale trains and track accessories.
The kits illustrated below were confirmed to be 0 gauge, but I suspect they are large scale.
