A locomotive which has taken 15 years and £300,000 to build has enjoyed the first-ever trip under its own steam.
The Lyd chugged into action across The Cob at the Ffestiniog and Welsh Highland Railway in Gwynedd.
It is the first entirely new engine to be built at the Boston Lodge Works since the David Lloyd George in 1992.
It is a replica of the original Manning Wardle locomotives which used to run on the Lynton & Barnstaple Railway in Devon.
The Lyd's maiden journey took place on 5 August and saw it terminating at the Ffestiniog Railway's Porthmadog Harbour station.
The engine was put through its paces by shunting five carriages.
It will now undergo further trials ahead of its first public duties at the Welsh Highland Railway Superpower gala in September.
Although the Lyd will mostly be a fixture on the Ffestiniog and Welsh Highland Railway between Caernarfon and Blaenau Ffestiniog, it will also make frequent visits to Devon.
The Ffestiniog Railway claims to be the oldest independent railway company in the world and was founded by an Act of Parliament in 1832.
