- Hello,
-
- A torpedo is a signalling device used as a stop indication for trains. It
- is about two inches square and about 0.5 inches thick and has metal straps
- on two sides. The straps are used to keep the device on top of the rail.
- The torpedo contains a pressure-detonated explosive which, when run over
- by a train wheel, will make a noise similar to that of a cherry bomb.
-
- Torpedoes have been known to cause a number of injuries. When I worked on
- the Western Pacific in the early seventies, I knew a brakeman who lost part
- of his hand merely by picking one up from the step of a caboose. They have
- been known to punch holes in motorcar wheels and even derail a motorcar.
- I used to carry them in my motorcar but no more! I do my signalling with
- flags, fusees and radios.
-
- Cheers,
- Greg WB6UHH
