The top photo shows an older style metro train, and the lower one was taken inside a newer one where there are no divisions between the carriages …. and it is designed to stop at specific openings at a clear barricade fixed to the station, see the lighter coloured screen in front of the train.
I like the curved tunnel walls, and really enjoy seeing the trains snake around on their winding tracks.The Paris Metro is a brilliant system, with trains on every line only a few minutes apart. The semi-circular walls create some problems for the poster hangers!
Tomorrow we leave Paris, but our trip home will take a whole week, so there will be more adventures and meetings with good friends along the way.
