This week's theme was: N is for Never again!
This nearly stumped me, until this morning, desperation led to inspiration.
The Mawddach Trail was one of the railway lines that succumbed to the Beeching Axe in the 1960s. It has now reinvented itself as a walking and cycling trail, as featured on a few TV programmes, including Michael Portillo's railway journeys following his trusty Bradshaw's guide.
Never again will a train run along this track, but I wondered what it might look like if one tried! :)
