Gosport Railworks is a specialist online shop offering 3D-printed railway models and accessories for model railway enthusiasts. Its range includes models designed to fit ready-to-run chassis, as well as fully 3D-printed vehicles that represent subjects less commonly produced by major manufacturers. The shop aims to make its kits accessible, with most designed for straightforward assembly, while noting that some projects are more challenging. This approach helps keep costs down and invites more people to enjoy building and operating model railways.

Products include locomotives, coaches, brake vans, multiple units, bogies and buffers, with designs drawing on railway companies and eras such as LSWR, GER, LBSC, Southern Railway and British Rail. Featured items include historic locomotive classes, corridor coaches and Island Line stock. Gosport Railworks also provides customer information through FAQs, shipping and returns details, order-status resources, a customer gallery and contact options. Its catalogue is updated with new products, and the shop welcomes customers to browse or create an account for online shopping.
