Our 2.5 yo has been very interested in trains recently. We went for a day out in Lucern at the Verkehrshaus in Lucern and although we had a great time the trains turned out the be a let down, kind of. There are beautifully maintained locomotives but they are mostly to look at, not to climb on.
Can anyone recommend or know of a park where train cars can be climbed on / explored by the little ones? Cargo wagons, locomotives etc...
Steam locomotives? There are several historic trains around Switzerland. You travel in the train and can take a look at the locomotive at every stop. So, yes, you and your kid can climb on it
A few minutes' walk along the lake, there's a lovely swimming area with a playground and a small, sandy beach, a small outdoor café, lockers and hot showers. https://www.stadt-zuerich.ch/ssd/de/...katzensee.html
Those miniature trains are usually called "GartenBahn" or "LiliputBahn", miniature trains that are still large enough for people (typically children) to climb on and ride.
Probably a bit early, but the Tram Museum Zürich may become interesting later on. Same for the Locorama and the Saurer Museum by the Bodensee.
I just noticed that thread name includes "for kids" and I'm talking about the steam locomotive pulling a bar car with a huge absinthe fountain screwed to the bar (for safety). First trip of the season tomorrow 30.04.2022
Something else to climb on can be found in Fisibach AG (not to be confused with Fislisbach AG): Trucks, excavators, steam rollers, and bulldozers. All at the Ebianum .
Around Zurich, my first try would be the Tram Museum. I used to take my son there when he was about the same age or younger. He didn't know exactly what he was seeing, but he liked running and climbing around. There was a fairly large Brio set in the middle of the floor that kids could play with too.
You can also make a walk over the train yards in Rapperswil. From the overpass, you can see all kinds of train stuff going on. And even get fairly close to the cars. Climbing and being up that high can be fun for a kid too. Think about combining it with a trip to the Zoo there and its a short walk from the parking area.
I also seem to remember two train cars in Uster that were available for climbing and touring. I think it had something to do with the model railroad association or something there.
The Polybahn might be an option as well.
I dont know of anyplace around Zurich where you can regularly climb around on actual full size working trains.
Timetable is out for 2022 - basically every last Sunday in summer.
Some people like to dress up in old clothes for the experience and it is possible to see the train / trains up close when they come in and out of the station and when they are preparing it for service at the beginning of the day. We have combined it with going on the bus and normal train to get there - our kids at 2.5 half enjoyed travelling on public transport as an experience as they don't do it on a regular basis living outside of the city.
This option that was already mentioned in this thread by Tom was also enjoyed by my boys. There are other things to do as well as ride on the mini train so this helps with the entertainment.
Toni's Zoo is five minutes down the road too which is great for kids.
(Although when we there last a few weeks ago, my kids went around with a notepad and pencil and measured all the cages to see if they were big enough!)
At the GZ Bachwiesen in Altstetten / Albisrieden there is an old traction engine in the park area that children clamber over. It isn't mobile - but my little one used to play on it.
