LOL...because that platform is attached to the clear archway on the left...it looks like its floating in air. Maybe those are round blue vacuum tubes where passengers step in and are sucked to Platforms 2&3. 
What I always find questionable is they make so many places for PlaKids to connect on sets like this but include none with it. Do they assume that everyone has extra PlaKids laying around? I would find this acceptable if Plarail offered packs of PlaKids for sale say in 5 or 10 packs. They don't have to be special ones, just the generic ones that are the most common so the others are still collectable. What if these are parents just starting to buy a young child Plarail toys and the Child says they want to play with the station like it is shown on the box with lots PlaKids....what do they tell them? Sorry honey...you can't have them because Plarail doesn't sell them. Come on Plarail...help the poor child out.
