Hemi, Right in the center of this: http://maps.google.com/maps?q=Niles,+OH,+USA&ie=UTF8&ll=41.181143,-80.757733&spn=0.001383,0.002232&t=h&z=19&iwloc=addr&om=0 The foundation and floor tiles are still there.
Not a tower, but they did interchange with both the B&O and PRR at this location. Also a branch of the Erie left the mainline right in front of the station. Plus there was a scale track to weight steel products. I was a busy place. The Ohio Central still runs through to switch the lumber yard and the GE plant.
