Llangadog "Heart of Wales Line"

[Do keywell]

I am just about to start an N Gauge model of Llangadog station and goods sidings. I am basing it on era5 from 1959( place name changed in 1958) and all sidings are removed by 1966. so a tight window. I have all the available books on the Central Wales lines and have photos of both platform building, the GWR signal box and have found a photograph of the goods shed. but bar that I am at a loss. I know that there was a crane and cattle dock but I know of little else.I have the WR track planes for the line.
I will drop into the activist when we next travel to Wales but in the mean time if anyone has any information or photographs on the once fairly extensive sidings I would be grateful. I can remember playing in my Grandfathers saw mills and coming across goods wagons. as far as I know John Lilly did not have a private sidings.
Everything has been obliterated over the past decades as it has on most lines that actually survived Beeching
