Is there a stadium capacity cap??

I'm currently building the biggest stadium which I believe is the 211000 capacity one & was wondering if that's the last upgrade available. I've already got 560,000 fans & I think they need to give us another upgrade or 2 for the higher level. Even the car park needs more upgrade levels. It's currently capped at 15,000 cars. Need to at least double that.

no stadium in the world better than 200k. why put those things in games

What would be better is a train or metro/underground station. Suggested it in the past but nothing came of it.
