About Us
Founded in the early 1970s when Ian Welch and a small group of dedicated enthusiasts set out to save steam, Mainline Steam Heritage Trust has grown into one of New Zealand's most respected custodians of mainline heritage. As a dedicated charitable trust committed to rescuing, restoring, and operating historic locomotives and rolling stock, the Trust believes rail history is meant to be experienced, not just observed.
Â
Under Ian Welch's leadership, skilled volunteers and engineers across regional depots like our Plimmerton base have spent decades undertaking complex overhauls to bring heavy steam engines and classic passenger carriages to full mainline certification. Today, our flagship excursions pair this living engineering legacy and raw mechanical power with modern carriage comfort and premier regional hospitality, taking guests on unforgettable journeys across the high volcanic plateaus, dramatic river gorges, and rugged coastlines of New Zealand.
About Us
Mainline Steam Heritage Trust is dedicated to keeping New Zealand's rich railway history alive and thriving on the open tracks. Operating out of our established Plimmerton base, alongside our soon to be completed facilities in Mercer and Canterbury, the Trust rescues, restores, and maintains an extraordinary fleet of historic steam locomotives and passenger carriages. We believe that true heritage should be experienced rather than merely observed, which is why every excursion pairs authentic mechanical engineering and the raw nostalgia of steam with modern carriage comfort, broad panoramic viewing, and premier regional hospitality.
​
To bring these magnificent machines to life across the national network, our excursions are operated in close partnership with highly skilled KiwiRail drivers and qualified mainline rail crews. Combining decades of preserved heritage with professional operational standards, these experienced drivers bring deep route knowledge and technical expertise to every trip. Together, we ensure every journey across New Zealands dramatic landscapes, from volcanic plateaus to sweeping coastal passes, is delivered with absolute safety, smooth precision, and timeless railway tradition.
Ian Welch - Founder
At the heart of the Mainline Steam Heritage Trust stands the unwavering vision of founder Ian Welch. What began in the 1970s as a profound personal dedication to rescuing vanishing railway history evolved into a monumental national mission. Under Ian Welch's leadership, the Trust transformed from a small group of passionate advocates into one of the most formidable custodians of heavy engineering and vintage rail.
​
Driven by the belief that magnificent steam locomotives belong where they roar best, out on the open mainline rather than static behind glass, Ian Welch spearheaded the rescue, acquisition, and meticulous restoration of countless historic machines. From bringing iconic New Zealand steam classes back to life to orchestrating landmark international locomotive acquisitions, his hands on approach and uncompromising standards for mechanical excellence have ensured that the golden age of steam remains a living, breathing reality on the New Zealand rail network.
