The world's first preserved railway celebrates its 150th this weekend.
The Talyllyn runs from Tywyn, near Aberdovey, for more than seven miles to two villages in the south Gwynedd countryside.
Watch the report from Rob Shelley below:
it was back in 1865 that Queen Victoria gave permission for a very small railway line to snake its way up an equally narrow valley in Gwynedd.......
So down at Tywyn's wharf station - the mothership of the Talyllyn - three engines who between them are more than 400 years old were making a right display of themselves.
At the other end of the line - in Abergynolwyn - actors Timothy West and Prunella Scales joined in the celebrations.
The whistles are set to echo across Tywyn throughout the weekend...
