What is UP going to do about the upcoming Positive Train Control requirement for their steam fleet? Will they install the technology on the equipment or use a trailing/backup diesel? I'd hate to see a diesel behind the Big Boy just for PTC (or for anything else). I'm aware that some groups are planning on installing it into their locomotives, like the FWRHS with NKP 765, some are planning on using a trailing diesel, like NMSL&RHS with ATSF 2926, and some are completely silent on it, like the UP Program.
