What are the similes in song heartless by Kanye West?

* "She told me her name is Faith, so I took her home / She gave me a feeling that I'd never known before / She made my heart melt like an ice cream cone"

* "But now it's like I'm standing at a crossroads / Should I try and fix it or just leave and let go? / I'm about to blow, like the 7:30 train / Can't stop moving in this open lane."
