Maybe they're meaning to put in an'idiot-proof' system That's correct. It is a business decision. Depending on how you work the numbers, it is more cost-effective to put your reliance into the mechanism and use less trained/skilled people than to use simple mechanism and expensive people. Machines are easier to control and if you get tired of them they are easier to replace. NYCT train apparently unintentionally keyed by a red signal Yes, that was a fluke...basically amounted to not seeing the signal. But much more clear-cut cases of misunderstanding "RESTRICTED SPEED" have happened in the past few years, thankfully none resulting in passenger fatality. I wonder if LIRR is an oddball; I seem to recall that their '75' codes something like 25-35 mph, at least in EMUs. The LIRR follows typical railroad ASC practice. Their 0 code is restricting (15) and 75 code is medium (30). Not that the code rate is something the engineer needs to worry about. |
