Above me sits a Seeing Hill, that rises to the sky, try to guess my longish name, what city am I?

Question

Here is a rhyming riddle I came up with only a little while ago.

---

My first four letters love to talk,
the next three like some sun,
the next pair are quite interested,
the last, a State, we’re done.

I am a city in a state,
above the one before,
our football team is really strong,
Blue fire from the core.

Above me is a town of stone,
where crimson waters fall,
My residents they often hear,
A locomotive's call.

What city am I?

Answer 1

You are:

Chattanooga

My first four letters love to talk,

Most people like to Chat

the next three like some sun,

If you go out in the sun, you might get a tan

the next pair are quite interested,

Someone interested, might say "Oo!"

the last, a State, we’re done.

State could mean country, or US state. In either case, Ga is Georgia

I am a city in a state,
above the one before,

Tennessee is north of Georgia

our football team is really strong,
Blue fire from the core.

This is the state football team - the Tennessee Titans, who have a logo with blue flames

Above me is a town of stone,
where crimson waters fall,

This is Rock City and Ruby Falls.
Which are both at Lookout Mountain, which is the "Seeing Hill" referenced in the title.

My residents they often hear,
A locomotive's call.

This is the famous Chattanooga Choo-choo immortalised by Glenn Miller
