Not familiar with that ATCS area, but for the most part, ATCS signals can be sporadic for server sites because the trackside "stations" are 900Mhz and only 5 watts. Most server ops don't have 300 foot towers with high gain antennas and preamps, so we miss signals from time to time. It is also weather dependent, at least on the 1st district
.
Wire line is bad news for ATCS. That means the signals are transmitted via underground lines, and not over radio. We cannot get those signals, so they are not displayed
Hope that helps a little bit.
