I model china clay trains in the west country in all eras (depending on what I feel like running) 70s BR blue diesels is a firm favourite at the moment with plenty of clay hoods!
I have a 4mm scale 00 gauge layout which I have been working on since October 2011, it's based on china clay operations in Cornwall
I also have a 16mm SM32 narrow gauge garden railway with live steam and battery locos.
I'm going to a place called Reading, then to somewhere called Feltham, then to somewhere called Waterloo, then to somewhere called Canning Town, then to somewhere called Custom House.
I'm staying in the Travelodge there.
