The heritage

A brief history of Märklin HO

Märklin, founded in Göppingen in 1859, revolutionised model railroading by introducing the HO scale in the 1930s. Their precision-engineered locomotives became the gold standard for collectors worldwide — capturing the character of real railways in miniature form.

klinnect is built to honour that legacy. Whether you're a seasoned collector with hundreds of models or just discovering the hobby, this platform gives your collection the home it deserves.
