Consultancy The Works has begun the design stage of the 4.5m extension to the National Rail Museum in York.
The Lottery-funded project is the first major investment in the museum for a decade, with the extension occupying the site of the old engine works close to York Station.
Chris Meehan, project manager for the Leeds consultancy, says its brief is to highlight the UK’s railway heritage through active displays for visitors, who will be able to watch work on historic engines from a raised gallery.
The project includes Monolith display panels, curved graphic panels and audio visual units, all created exclusively for the museum.
Builders handed over the site to the six-person design team this week. The extension is due to open in July.
