It's not a font. Ultramodern is similar as is Binner. As far as I know, there isn't a font that looks exactly like or even close to your sample.

I don't know what you need to do with this, but Britannic Bold http://www.fonts.com/findfonts/detail.asp?pid=403485 with some negative Squoosh�(squetch??)applied would give a very similar effect.

See also Benn Coifman's Illinois Central (he makes
train related fonts). It will get you, I think, closer to the
hardest letter to match, the S.

Nice find. It's a bit crude, but reasonably close.

I just remembered another one: Magnesium. It has the right overall feel, but some of the details (like the poiny A and N) are different.

Thanks, everyone. Very useful insights. The project is a personal one to record mosaic artwork in a local subway system.
