WebFeb 17, 2008 · As you may know, postwar whistles are activated by something called a slugged relay, which will only close when DC voltage is present on the track. When the relay closes, it puts full track voltage to the motor. Sometimes, some sort of problem in the relay will keep the motor from getting full track voltage. WebJul 12, 2024 · Lionel usually uses a nichrome resistance wire in this application. The resistance wire is usually attached to a copper wire at both ends with a crimp butt splice. The resistance of this connection can go up with age, reducing the amount of AC power that can bypass the rectifier.
WebThe relay is an electromagnetic coil energized by Direct Current, or DC power. When DC power is injected into the track power, the relay coil draws a metal plate up to it which completes a circuit for things like a battery powered horn or track powered whistle. When the coil is no longer energized, gravity drops the metal plate back down. WebOnce the horn and battery bracket are installed on the frame, test the horn by inserting a battery and touching the horn lead to any part of the bracket. This is also a good time to adjust the horn for optimum pitch. When you solder connections to the relay, put the locomotive on the track and test the relay. Lionel 8950 FM.
WebThis Identification Guide for Lionel Electric Trains covers the "Post-war Era" only from 1945 until 1969. The Whistle Controller No. 167 would evolve from the pre-war No. 166. The need for this controller began in 1935 when … WebThere is a rectifier in the transformer, and a seperate relay to activate the whistle mechanism located in the tender or in the disel locomotive body. Now this is how the …
WebJan 9, 2015 · Lionel has a modern version that has a DC motor and controlling board. If you care to research it. The relay will need to be isolate too. Only the coil connections will have track power. Then you ground back to your bridge. I guess.
