I came across this 2 minute time lapse video of Chicago's five track Deval Diamond being replaced. Thought it was interesting to see how this is done.

We would have install asphalt under the diamonds for better and future draining. Did a double diamond in less than 8 hours, and that was running trains with signals on both tracks.
Thanx for posting that video. Very interesting!!
Interesting video. Thanks for posting.
Cool! Thanks! I've been through there hundreds of times on the METRA commuter trains downtown and back. I miss the old DeVal tower, of course. Time marches on. Thanks for posting!
