Here's an example of a fairly compact EAF mill, Nucor Steel in Seattle, crammed in between residential streets and a bit of urban motorway, a surprisingly public venue for something like a steelworks! One interesting feature of this one in particular is that the lines to access the yard from it's supporting yard actually run through one of the structures, so you could present it as a standalone layout almost - and whilst it's still a large industry, it's not so large that it couldn't be modelled...

Lots of images come up if you do an google image search on 'Nucor Seattle' - and Youtube has some shots of their fleet of GE's.
These were shot in the exchange yard the other side of the motorway viaduct (parrallel to Harbor Ave SW) but give an idea of current car types - check the overhang on the flatcar on the second vid! Long cars and 'trainset' curves combined!
