Many thanks to Pat for hosting this week. Another good theme that I don't recall us ever doing before. Had to have a think about this one, but found some good examples in my archive.
1) Locomotive on the Snowdon Mountain Railway, North Wales.
2) A fun machine!! The Montu rollercoaster, Busch Gardens, Florida.
3) The inside of a washing machine!!
4) Machinery raising a road bridge, Cardiff Bay, Wales.
