About TrainDex
The marketplace aggregator for HO scale model railroaders
Our Mission
TrainDex makes it easy to find the HO scale model trains you're looking for. Instead of searching eBay, hobby shops, and dealer sites one at a time, TrainDex aggregates listings from multiple sources into a single search — so you can compare prices, see what's available, and find the best deal.
Beyond marketplace search, TrainDex maintains curated reference databases for HO models, real-world prototypes, manufacturers, and railroads — giving hobbyists a central place to research equipment before buying.
