A couple of photos and a few bits that I used for inspiration. One was an article in the March 1986 Modern Railways which includes a feature on the regeneration of the Welsh Valleys lines - of which Rhiw was an imaginary section. The period is 85-89 just prior to privatisation and post miner's strike when the Valleys (supposedly) had money pumped into them; new passenger services were planned on old freight lines and the (then) new Sprinter units were coming on-stream.
Rhiw appeared in the July 2012 Railway Modeller.
The layout was broken up in 2014 after attending several exhibitions.
