Concrete Compressive Strength vs Time
They probably poured 3,000 to 5,000 psi concrete
1 Day - 16% 480 to 800 psi
3 Days - 40% 1,200 to 2,000 psi
7 Days - 65% 2,000 to 3,250
14 Days - 90% 2,700 to 4,500
28 Days - 99% 2,970 to 4,950
A large locomotive has a axle load of up to 70,000 lbs.
The contact patch between the wheel & rail is about the size of a dime. “Eric Magel, Joe Kalousek, Mike Roney, “Stress reduction, railroad style: the contact area where wheel meets rail is about the size of a dime. Making it as stress-free as possible can save big dollars”. Railway Age, July, 2002.”
Unless they wait two weeks to do anything about this sabotage, I’d guess you could just slowly drive a locomotive over the spot and break up the poured concrete.
Any railroad engineers out there to confirm or refute this?
I doubt the railroad would authorize an engineer to just drive over the obstruction to clear it. It’s just too risky.
But busting up uncured cement wouldn’t take long for a couple of jack jockeys.
And I’d keep track of every cent it cost to clear the track so that when these pussies are caught, they can get the bill. Maybe put them to work chopping weeds from the right-of-way to work off their debt.
