A system for use by a railroad to warn railroad workers, track walker, railroad personnel and others of oncoming train(s) and to warn the train operator(s) of such train(s) of the presence of railroad workers, track walker railroad personnel, other train(s) and others on or near the railroad tracks, such system including at least one train transceiver for each train for sensing signals transmitted by at least one of a plurality of personal transmitter/receivers, one personal transmitter/receiver being worn by each of such railroad workers, track walker and railroad personnel, such train transceiver(s) to warn the train operator(s) of the presence of railroad workers, track walker, other train(s), and railroad personnel on or near the tracks when receiving signals from the personal transmitter/receivers, such personal transmitter/receivers receiving signals from the train transceiver(s) to warn the railroad workers, track walker and railroad personnel of oncoming train(s) with such warning signal activating nearby lights and horns, such system working in conjunction with VOBC and a compact, lightweight portable train detectors.

Claims2

Dependent claims

A system for use by railroads having a train, tracks, a train operator, track walker, railroad workers, railroad personnel and others, comprising:

warning means for alerting said railroad workers, and railroad personnel and any others working or present near said railroad tracks to the presence of an oncoming train on said railroad tracks and for alerting said train operator of said oncoming train of the presence of such workers, railroad personnel or others on said railroad tracks, said warning means including:
a plurality of personal transmitter/receivers, one of said personal transmitter/receivers for positioning on each of said railroad workers and railroad personnel, said personal transmitter/receivers being battery-operated, said personal transmitter/receivers for receiving signals indicating the presence of an oncoming train, said personal transmitter/receivers providing a perceptible indication to each of said railroad workers of said oncoming train when receiving said signals, each of said personal transmitter/receivers transmitting signals for indicating the presence of train workers working on said railroad tracks;
a train transceiver disposed on said train, said train transceiver viewable by said train operator and railroad personnel, said train transceiver for receiving signals transmitted by each of said personal transmitter/receivers carried by said railroad workers and railroad personnel, said signals from said personal transmitter/receivers indicating the presence of said railroad workers on said railroad tracks, said train transceiver having means to alert said train operator of the presence of said railroad workers, another train, railroad personnel and/or track walkers on or near said train tracks, said train transceiver further including a signal transmission means, said signal transmission means sending signals to any personal transmitter/receivers able to receive said signals to warn said railroad workers and railroad personnel of the presence of an oncoming train on said railroad tracks, said train transceiver signals activating said personal transmitter/receivers to produce said perceptible indication to said railroad workers and railroad personnel for warning them of said oncoming train and at the same time activating any warning lights or horns nearby;
a VOBC and a tag reader disposed on said train;
at least one tag placed by said the railroad workers near said track in advance of said work zone for activating said VOBC and slowing said train when said tag reader on said train reads said tag;
wherein said activated VOBC sends a signal to said transceiver on said train which transceiver notifies said train operator and said railroad workers on said track of said oncoming train.

3 more elements

A personnel warning method for use both by railroads having a train, tracks, a train operator, track walker, railroad workers, and railroad personnel, and by others, comprising the steps of:

disposing a plurality of battery-operated personal transmitter/receivers on each of said railroad workers, railroad personnel and/or others, said personal transmitter/receivers receiving and sending signals;
disposing a train transceiver on said train, said train transceiver viewable by said train operator, said train transceiver receiving said signals transmitted by each of said personal transmitter/receivers carried by said railroad workers, track walker, other train(s), railroad personnel and/or others, said signals transmitted by said personal transmitter/receivers indicating the presence of said railroad workers and/or railroad personnel on said railroad tracks, said train transceiver further including signal transmission means, said signal transmission means sending train transceiver signals to any personal transmitter/receivers able to receive said train transceiver signals to warn said railroad workers, track walker and railroad personnel of the presence of an oncoming train on said railroad tracks, said train transceiver signals activating said personal transmitter/receivers to produce a perceptible indication to said railroad workers, railroad personnel and/or others for warning them of said oncoming train;
alerting said railroad workers, track walker, railroad personnel and/or others working on said railroad tracks or in the vicinity of said railroad tracks to the presence of an oncoming train on said railroad tracks, said step including receiving train transceiver signals on said personal transmitter/receivers, said train transceiver signals indicating the presence of an oncoming train, said personal transmitter/receivers providing a perceptible indication to each of said railroad workers, track walker, railroad personnel and/or others of said oncoming train when each of said personal transmitter/receivers receives said train transceiver signals, each of said personal transmitter/receivers transmitting signals to said mounted train transceiver for indicating the presence of railroad workers, railroad personnel and/or others working on said railroad tracks or in the vicinity of said railroad tracks;
alerting said train operator of the presence of said railroad workers, railroad personnel and/or others on said railroad tracks or in the vicinity of said railroad tracks by said train transceiver receiving signals transmitted by at least one of said plurality of said personal transmitter/receivers, said train transceiver producing a perceptible indication for alerting said train operator of the presence of said railroad workers, track walker, railroad personnel and/or others on or near said train tracks;
providing a VOBC and tag reader on said train;
placing a tag near said tracks by said railroad personnel in advance of said work zone for activating said VOBC and stopping said train when said tag reader on said train reads said tag;
and
sending a signal by said activated VOBC to said transceiver on said train which transceiver then notifies said train operator and further sends a signal to said railroad personnel on said track warning them of said oncoming train.
