Sound Doesn’t Work
I should have read the low rating reviews first. Many said the sound stopped working soon after use. Mine was dead on arrival. But I think I will keep it since it is a nice addition to the other Brio set.

Not functional on its own…
Don’t make the same mistake I did and not realize that the sounds and such won’t work without having to buy the $50 smart tech Brio train 😑

What a pain
Like others, I bought this w/o realizing I had to also buy the smart tech engine and download the app, so I ended up spending about $100 for a 3yr old grandson's train accessory. His father is still trying to figure out the app and send me a video of the tunnel working, but I found one on YouTube and it's not very impressive. Live and learn - Brio is expensive and doesn't live up to expectations.
