OO Gauge IOA & JNA Wagons

IOA Prototype

The Romanian built IOA wagon is a type of high sided open wagon designed to carry ballast and spoil. They were first released in 2009 and all carried the distinctive Network Rail Engineers yellow livery and were designated Mussel. The IOA had a maximum load capacity of 102 tonnes and usually travel in block trains of 10 wagons or more. 

JNA Prototype

A large fleet of 555 JNA bogie ballast wagons was built by Astro Vagone (part of the Trinity group) in Romania and was principally designed to carry ballast and spoil. The design incorporated a large reinforced door in the centre bay to aid inspection, discharge and cleaning. The fleet came into service in 2004 and are now a common site nationally in their distinctive yellow engineers livery of Network Rail. They commonly operate in rakes of five and have been given the nickname Falcon
