Some more details to djk's overview.
1. In rural areas of Belgium 3 x 230 V TT is still pretty common (no neutral, no ground supplied). RCD is therefore mandatory. Personally I know a lot of those installations in the area of Eupen (very East).
2. Also in Germany there are a few transformers left, some of them private owned ones. They usually provide 3 x 230/133 TN as described above, 133 not in use anymore.
3. In Central Europe two voltages (now 230V/400V)remained very common, being typically used for oven/ranges. But only Swiss appliances are only 400V, other ususally use a Y arrangement and 230V for the heatings.
