So why should the RR's pay for something that they can't install without permission, something that is clearly the domain of the local city/state DOT departments by law, not to mention something that they have no use for?
Simple: because these devices are intended to lessen the impact their operations have on the communities they run through.
Why should the community fit the bill for the railroad's decision to operate?
Because the community is crossing private property. Consider the following:
You own a large farm next to a small, but growing town. The town comes to you and says, we need to build another road to get to/from downtown and we'd like to build that road through part of your farm bisecting your fields in half. Ten years later that road is so busy that you can no longer drive from one section of your farm to the other, since you can't get across the road.
So you go to the town and say "please put up a traffic light, so that I can cross the road." The town now looks at you and says "we'll be happy to do that if you pay for it." Unless you were totally desperate, you would not pay for that light. You would expect the town to pay for it, especially since you were already nice enough to allow them an easement on your private land in the first place.
Yet, that is exactly what you are asking the RR's to do. You want a private company to pay for warning devices so that people can have the privilege of crossing the RR's private property without getting killed because they refuse to obey the laws of this country. Laws by the way that aren't new, they've been around for well over 100 years now.
People move next to an Interstate Highway, and then demand noise barriers. People move next to an airport and then demand noise abatement procedures, which leave pilots doing stupid and odd movements while trying to get a plane into the air, like in Chicago.
Exactly! It's not so bizarre a notion that any creator of loud activity has a duty to minimize his impact on the surrounding community. Whether it's private citizens practicing for their soon-to-be-famous band in their garage, or cars who must install (and pay for) legally required and approved emissions management equipment, or airplanes taking less convenient routes (and thus paying that cost), it's a pretty generally accepted position that one should not force the whole community to live with unnecessary noise.
If the noise creator was there first, then YES, it is a bizarre notion. If the houses were there first, then NO.
Perhaps I should have been a bit clearer with my original statement. I should have said "build" instead of "move".
Or in other words, when people build houses at the end of the runway at O'Hare airport expecting that it won't be noisy, then yes, they should suffer the consequences. Instead each day pilots perform a series of tight turns, throttle backs at a time when they're trying to get the plane in the air, and potentially endanger hundreds of people’s lives, all because some developer saw cheap real estate and people were dumb enough to buy those houses expecting quiet.
In a large city when an Interstate comes through, I have no problem with using general wide spread tax payer monies to build sound walls. But when the highway was already there for 10 years and again someone comes along and puts up a house next to the noisy highway and then complains, I have no sympathy. If they want at a sound barrier, then they and their immediate neighbors can pay for it. But I don't want to see my tax monies being used there.
I've watched for over 30 years this phenomenon in the State of New Jersey. There are about 4 highways in northern NJ that I can name where the houses where there before the highway and I agreed with those walls going up. But for miles and miles of I-80, I-78, and I-287, the highways came first and were originally built without sound walls. At least until stupid people built houses next to those highways for the ease of a commute to NYC and then suddenly realized that "hey, highways are noisy." And now millions of tax dollars have been wasted building sound walls for those people who couldn't figure out ahead of time that living next to a highway might be noisy.
