Dinas-based NG15 No. 134 has been undergoing running in after its lengthy overhaul in North Wales, and we spoke with Adrian Strachan to find out whats next.

Back in September, the locomotive appeared at the Ffestiniog and Welsh Highland Railway’s Super Power Event as a soft launch for the locomotive, where it was in light steam on display for photos.

Since September, over 200 miles of running in have been completed, and Adrian says that only very minor adjustments have been made.

Through the Autumn, the locomotive has successfully been gauged between Caernarfon and Rhyd Ddu.

More recently, the locomotive has taken on a loaded test run of 8 empty WHR saloons, where the locomotive proved the master of the winter railway, with no sanding required on the 1-in-40 grades.

The loaded test run was also proving that the locomotive’s newly completed spark arrestor worked fine.

Adrian finished by telling us that higher loads and more gauging runs will be completed during the spring when operational restrictions allow.

More information on the locomotive and donations towards the project can be found here.
