Apart from a small part of the Seibu Shinjuku line (Nakai-Numabukuro) aren't most track changes planned or in construction ground level tracks being elevated? AFAIK the Odakyu rises again after Shimokitazawa?

There's a few more going down but you're right, sadly, more are going up. That's nice when riding but mostly sucks if you live near them.
