I would cautiously say that CBTC is a safer system thanwaysides signals and trip, on the average. BUT, whenever you dumb it down there is a long-term risk that the operating personnel will sink to the level you set for them. When that happens, you have a degraded ability to respond in the field to unusual situations. Most accidents with PTC systems are not because of "false-clear" signal failures, but secondary things which happen during failure work-around, or out of the ordinary moves. |
