Is subway construction like highway construction where they just constantly rip stuff up and replace it just to keep busy?

Over the period of a day or two, I noticed constuction crews ripping up a line of tracks, and then replacing them with new ones. They completely demo the concrete and railroad ties. Then, they pour fresh concrete, and put back the ties. The tracks didn’t look bad in the first place.

Each track must be on some sort of a replacement plan. Maybe it is like Verizon’s “New Every Two” deal. Hey, if it’s a saftey issue, I’m all for replacing the tracks. However, something smells a bit like a labor union to me…and it isn’t the homeless guy (although they do smell similar).

Live from the subway, back to you in studio…
