As I am riding PATH more and more going to red Bulls MLS games in Harrison, I can't help but wonder why PATH has extremely sharp curves in some places, especially approaching Hoboken. What was the reason for this?

So they didn't have the ability that (for example) NYC did with the IRT to use eminent domain to obtain property rights. If you couldn't get permission to dig under someone's property, you went around it.
These tunnels were never intended for full size trains, but only for smaller transit-sized cars.If you're talking about what was built or completed by the H&M, sure. The original 1874 plan was for full-size freight cars. If you watch carefully in tunnel A (Christopher St. to NJ) you'll see it getting wider in a couple steps, until it achieves its full size near the "15th Street Shaft" sign. The step-down to smaller sizes is concentric, so you don't see a jump to a much larger tunnel size (the trackbed is in the same place). It is a lot more apparent if you can catch an train running in the opposite direction (sometimes during late night work with single-track operation). If you look closely enough, you'll see that the side walls of tunnel A in NJ are brick. That's really the inside of the outside - 6 courses of brick behind a 1/4" iron plate (which has likely rusted away in the past 128 years - it was just there to hold back the silt while the brickwork was laid).

If I can see that from inside the car, then certainly the engineer can see them as well, and knows that the signal is about to change, so no need to slow down or stop. At least that's what I thought when I rode the PATH regularly, er, in the previous century.NYC subway signals work the same way. The last paragraph on the following page explains what you saw.
