The original locomotives, designed by William Paton Reid, were some of the largest Atlantics to run in this country. Built in three batches between 1906 and 1921, Evans' model is based on the final stage of design.
An older engine, well built in the first place although having seen a good deal of use - it's coming up to needing a bottom end overhaul, including some rebushing work and replacement of axlebox springs which are tired. That said, it's one of the nicest running engines we've seen in recent times - it steams freely and runs down to the slowest of tickovers, somebody did an excellent job of setting the valves.
The boiler has current club certification, with next hydraulic test due in August 2026.
A previous owner has blanked off the hand pump delivery pipe, the engine relying on axle pump and a pair of injectors, which worked faultlessly when we steamed it.
A good looking engine, a design that we rarely see - this is the first running NBR Atlantic we've ever had, having sold some castings for one back in 2016.
