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


The Dapol JNA-Y models feature:
• Utilising the Dapol OO Gauge MRA model as a base, with a new body and improved chassis, Bogies and buffer beams.
• Finely applied livery with accurately printed detail
• High level of detail on the body, bogies and buffers representing both MRA end and centre cars
• Profiled wheels for exceptionally smooth running
• Heavy dicast subfloor for added weight
• NEM pockets with self-centring couplings
