Bought from EWS in 1998/9 from Toton scrap line. Originally this loco was withdrawn due to weak springs, as it leaned out of gauge; prior to withdrawal it had its max speed reduced to 40 MPH.

When D5830 was purchased it had no windows, no radiator elements, and no batteries. It was initially bought for its power unit, which was to be put into 31418, a locomotive previously owned by the T1LC.

Following the purchase of D5830, it's overall condition was realised to be too good to be used purely for spares. After a vote of the membership, 31418 transferred to Boadicea Traction Ltd with a view to mainline re-instatement. Subsequently, 31418 has been taken on by A1A Locomotives Ltd with a full overhaul of the locomotive well underway. The power unit swap has taken place, using the unit from 31421, and overhauled bogies (from 31123) have been fitted. A selection of photos of this overhaul are on the excellent www.preserved-diesels.co.uk website.

D5830 was painted into Golden Ochre with no yellow warning panel for the Spring 1999 GCR Diesel Gala and numbered No. D5579. It is the only member of the class to authentically carry this livery. It has since reverted back to its original No. D5830 and has had small yellow warning panels added.
