Ya know, that may be the first right-angle culvert I’ve ever seen.

That’s interesting. Must not ever get much water moving through it. I can see why they would think it was a good idea so it didn’t wash out the tracks but hydraulically its horrible.

Devon, you hit the nail on the head. That is done to divert the flow and reduce the velocity of storm water running out of that drain line. Left to it’s devices with out the vertical leg, the damage to the road bed would be extensive in any heavy rain storm, It’s NOT SUPPOSED to be good for the hydraulics.
Finally got around to finding the location on Google Maps. Street View shows that the right-angle mod was done after image capture in September 2013.
It also shows the Street View car had a few leaves stuck to the north side of its camera dome.

I have no problem with a 90 degree bend, But it should be a sweeping bend. But I am also used to working with pressurized water systems not low volume low pressure drainage. I am sure it works just fine. But working with pipe design most of my life it just looks odd to see a pipe do that.
I have seen few examples like that beside I-64 where it goes through the Blue Ridge range. The same interstate also has some runaway lanes for semis.

I’m just shocked that the freight train has an actual CABOOSE in 2021! I didn’t know any railroads still used them.

Under normal flow calculations I would agree that a sweeping turn is better. But in this case, the INTENT is to damage the flow and generate turbulence, therefore the HARD 90.

Ray I had to go back after t reading your comment, didn’t pay a bit of attention to the caboose.
Side note, here in Phoenix the BNSF line has a wye near Grand ave and 43rd ave and they store a caboose there they use as a shove car. I need to take a picture of it as it is a well graffitied extended vision caboose
