This has been in the works for a long time. Prior to moving here, we had to decide between living near the highway vs. railroad. We decided to go central, and haven't regretted it. One of the deciding factors was researching the anticipated freight traffic along the UP line. Even back then, they were forecasting an increase of a higher volume of trains, a trend which has continued to this day. Given that we couldn't help but notice there were few overpasses, we said 'heck no' and haven't regretted living mid-town (well, it's mid-town today--it wasn't back then).
I don't know how receptive UP will be to those affected residents. This line is getting ready for some serious intermodal freight and a lot of money. Once the work is completed, I think they are anticipating around 50 trains/day (maybe 2,500 flat cars) in the near future with as many as 200 trains by 2025. That is due to the Triangle Railroad Holding Co. and their ability to push freight through the Texas Triangle (Houston/Galveston-Dallas/Ft. Worth-Austin/San Antonio) without it bottlenecking in those cities. Standing in the way of that money will be difficult.
On the other hand, it is good for the economy and reduces some emissions.
