Apologies if old news.
Read where the secretary of transportation is telling the RR to get PTC operational by Jan 1, 2016 or face hefty fines each day each train is operated without PTC. Claims RR are just stalling hoping to shake the congressional money tree. RR say come Jan 1st, they will shut down operations if fine will be levied.
Read on another thread about bandwidth limitations in the 220MHz band causing problems as well as backlog of antenna sites that must be approved on native American lands
Etc,etc, etc.
Wonder who will blink first?
