PROVEN reliable enough for route announcements, and EXPECTED to be JUST as accurate for CBTC.AFAIK, there is only 1 calibration point for the announcements - at the beginning of the run. That's quite a bit different than one in every station. Ever set up a network time protocol server on a network? The Linux version nptd recalibrates to a secondary NISC source every 20 minutes. The rest of the time it's dead reckoning. Ever wonder WHY us "railroaders" are snickering like we are? The perils of inbreeding. You've tried to shut out all post 1930's technology and listened only to your high priests. :-) |
