Yesterday may have been the end...

I believe most tracks will go under overall. They will be converted to housing complexes because that's what people want and they dont care about tracks.
All they need is a new housing track within earshot and let the noise complaints take off. Eventually, labeled as nucinse property and shut down. Sadly, very few will survive if at all.

This is so true. Just Google Hickmans Egg Farms in AZ.
Where I lived in AZ there was a small horse stable. Been there since the mid 70's or so. People build up around it. Owner put up all sorts of signs, please don't feed the horses etc. One snot locker got bit. City came out and told him he needed to put up a block wall all the way around it. Guy that owned it was an feisty sob. He built the walls....and seen to it that the entire lower corner had drain blocks. Every time we had a heavy rain....well....the gully in the road was full of horse crap. Neighbors started complaining. Tried to sure him. He just met them in court...with the plans for the fence....that had various City departments stamp of approval....:rofl::rofl::rofl::rofl:
