Bulla Hill Railway is operated by the members of Tullamarine Live Steam Society (TLSS). TLSS is a group of like-minded people interested in building and running miniature steam, electric and diesel locomotives. Members are also interested in model engineering including stationary steam engines and traction engines. Members come from all walks of life, with all sorts of skills and are all volunteers.We are a not for profit organisation. All funds raised are used to maintain and improve the facilities. The site has been progressively re vegetated with native plants with an aim to provide a natural bushland setting through which the railway operates.
