> 静岡県の伊豆は、キンメダイという魚や温泉などが有名な観光地です。  
>  Shizuoka's Izu is famous for hot springs and _some weird_ fish  
>  伊豆の海岸を走っている伊豆急行 **で** 、赤いキンメダイをイメージした電車の運転が始まることになりました。  
>  A train service, that looks like a red fish, will start running along the
> Izu coast, _run by_ Izu Express.  
>  たくさんの人に観光に来てもらうために、 **伊豆急行と** 近くの６つの市と町が **考えました** 。  
>  For the purpose of getting lots of people to come sight seeing, 6 nearby
> towns and cities **thought up the Izu express**

The part in bold in the last sentence is just a guess. I assume that と is
quotative here? I'm guessing that it was something like:

> [Izu express would be a great idea]と考える

but with "would be a great idea" omitted as being too obvious to everyone but
me. Is my thinking correct?

I also have a question on the second sentence. Does 伊豆の海岸を走っている modify 伊豆急行?
It feels to me like it should modify 電車の運転 but I worry that the comma prevents
that from being possible. Finally, is で 'by means of' here or copula. I think
it must by "by means of". If it was copula then we'd have " **It** is the Izu
express which runs along the Izu coast and ..." but we don't yet know what '
**it** ' is.



  1. I don't see the と as quotative. 
  2. The `伊豆の海岸を走っている` does modify `伊豆急行`. I wouldn't worry about the comma as those are suggestive rather than part of the rule like in Engish.
