Emergency Messaging, AM/FM *On Locomotive*
DHS has proposed a change in scenario. They want an on locomotive alerting
system that could be commandeered and driven at, near or about a disaster site. Everything else stays more or less the same, overbroadcasting on local AM/FM, power off the locomotive, selective or full frequency broadcasting, train (s) to be in motion at all times. 20-30 second messages that would also combine a message to be aware that a locomotive (at speed) will be flying by the at grade crossings. Comments? -- Drop the alphabet for email |

That would be much easier, simply sweep a modulated oscillator across the
band. With a couple of adjustments it would be easy to emulate a train whistle, a somewhat universal warning. wrote in message ...

Not the case - the power from a loco is, not surprisingly, applied to the tracks. Actually, it's not. What made you bring up tracks anyway -- my reference to the tracks on the lake falling in? My point was that the locomotive is going nowhere there aren't usable tracks. On a diesel-electric locomotive, the generator's output is applied, not to the tracks as you seem to think, but rather through control circuitry to the stator around the axle. It's rather amusing to see a repair yard worker with a set of wheels-and-axle (they're all one single piece, in case you didn't know) clamp a stator around the axle, connect a battery with a pair of short jumper cables and walk the whole arrangement across a concrete floor as though he were walking the family dog. BTW, at 4,000+ horsepower, you could plug in nearly anything a user might want, given proper appliances and the right plug. :-) The electric generators used for powering gear other than the train's vitals are not high power.

Like I said in another thread, "Emergency" implies IMMEDIATE (not planned)
danger to life, limb, or property. It seems that, in your proposal, you are PLANNING to use these frequencies instead of more appropriate ones. I would think that you need to create (and supply) a system that is isolated from broadcast frequencies. Wayne- (KC8UIO) "Ari Silversteinn" wrote in message ... DHS has proposed a change in scenario.

Whether or not the concept is valid, that's for DHS to decide and they already have. The driving force behind this, imo, is that during NOLA no effort was made to use the RR as a means of evac. Several of the lines offered but FEMA refused. Instead, Carnival made off like a bandit with 1/3 full ships but 3/3 full government pay. In order to evac, the RR would need to run flat out and with an evac traffic surge, crossings become more critical. -- Drop the alphabet for email |

I think you will find that the FCC has the FINAL call on frequency band
usage. I can't see them authorizing such intrusive use of the normal broadcast bands, especially after the broadcast industry gets wind of your proposal. From a technical standpoint, broadband transmission of a signal is not hard. A simple VFO sweep of all the normal broadcast bands is all that is required. Obviously, the appropriate modulation techniques would have to be used for each band. Another approach would be the use of a local (LOW power) sweeping UP/DOWN converter. In this method, you could transmit a specific (authorized) signal from the site. This signal would be received and detected by a local receiver. This information would be used to modulate and rebroadcast the signal within the vehicle. However, this would require onboard equipment. I still think that your biggest hurdle will a legal one.

Initially you said it was to be used at an emergency site, and now you're saying it's to warn of a high-speed train cometh. What the hell gives? Ken Both, there are three defined needs (today) 1) on locomotive, permanent at grade crossing and mobile, take-to-site-and-leave. -- Drop the alphabet for email |
