In reply to Walker Angell.

Working with Minneapolis last year we ran into several during repaving and rebuilding roads... and no, they cannot be used. Partly just because they didn't have good rail maintenance machines then like we do now, so they were entirely flat on top, maybe by design then, but now that would do damage to modern streetcars. Also, steel doesn't bind to asphalt, so there are cracks in the pavement over the tracks, letting in water with no easy escape. The ones we removed at Bryant and 46th were so rusted they looked like they were frozen mid-boil.
