This brought back memories today of 2003 when we came to Switzerland and travelled from Zürich to Interlaken on a train. Jude was a toddler and Isaac only 4, and we were delighted to find a playground on the train complete with slide and climbing frame. So unlike the UK! So you know where the playground is situated, there's a mural on the side of the train.
As an aside, good to be back in Switzerland with efficient transport!
