Dapol have announced a newly tooled range ex-MRA JNA-Y bogie engineers wagons in OO Gauge - including both inner and outer versions in Network Rail yellow!
These newly tooled models will replicate these modern era engineering wagons utilising the highly acclaimed Dapol OO Gauge MRA model as a base, with a new body and improved chassis, Bogies and buffer beams.
The engineering prototypes are currently being reviewed along with the artworks by the design team. Modifications that have been identified are to improve the buffer head profiles and remove any unnecessary holes in the side of the chassis. We anticipate that these models will arrive during Q4 2026.

Prototype Information
The JNA-Y, commonly known as the “Hawk”, is a modern Network Rail engineering wagon and a familiar sight on today’s British railway. Introduced through a large-scale rebuild programme, these wagons were converted from the earlier MRA side-tipping ballast wagons, extending their working life and aligning them with modern engineering practices.
Stripped back to their original frames and rebuilt with new steel box bodies, the JNA-Y offers a robust, high-capacity open wagon designed for loading and unloading by excavator or grab. The conversion programme, delivered for Network Rail in the early 2020s, has produced around 300 wagons, making the JNA-Y one of the most numerous contemporary engineering wagon types.
In service, JNA-Y wagons are used for ballast, spoil and general infrastructure materials, typically operating in long rakes behind modern diesel locomotives, but can equally be spotted operating singly. Finished in Network Rail yellow and often heavily weathered, they are an essential component of the current-era engineering scene, making them an ideal addition to any modern image OO gauge layout.
