Rail Miniature Flash is a French railway modelling magazine founded in 1962, known for its practical approach to the hobby and its coverage of miniature and real railways. Relaunched in a new format in 2019, the publication shares techniques, inspiration and specialist knowledge through articles written by contributors and experienced modellers. Its regular issues feature model-building projects, scenery and weathering advice, product tests, railway history, photographs and news from manufacturers and artisans.

The brand also publishes books and themed special editions, including practical guides for creating realistic model landscapes and illustrated histories of railway depots. Readers can explore magazine contents, browse archived articles, consult tables of contents, locate a newsstand or arrange a subscription through its website. Additional resources include downloadable materials, photographs, a model railway vehicle configurator and a community section. Rail Miniature Flash extends its coverage through a YouTube channel featuring conversations with modellers, craftspeople and enthusiasts, demonstrations and discussions about railway modelling.
