Pacific Fast Mail Sound Effects Unit

via this auction

"Pacific Fast Mail sound/throttle unit. Intended as a sound effects unit for an HO scale train layout and originally manufactured in the 70's I believe. Was featured recently on the Matrixsynth blog [see label below] because it is an analog sound gizmo of sorts. Will make fuzzy/warm noise based exhaust sounds and bell and whistle sounds. Unit does not have audio outputs. Instead it puts the audio signal into train rails via it's screw outputs and then into a train that is equipped with an amplifier and speaker unit. In other words you will need a Pacific Fast Mail sound module to hear the sounds (these are available on Ebay from time to time)."

Pacific Fast Mail PFM HO Sound System 1

via this auction

"Pacific Fast Mail Sound System I. This is a locomotive sound effect unit intended for HO scale model train layouts. This unit was featured recently on the Matrixsynth blog because it is actually an analog synth gizmo of sorts. There are no audio out ports on the back since the idea was to have the sound travel through the current in model train rails which would then be picked up by an amplifier/speaker located in a train engine. In other words, to hear the sounds you will need a Pacific Fast Mail amplifier unit or similar unit (not included) wired to the main unit. These have been known to pop up on Ebay. This auction also includes 2 Quadratape I units. These are essentially basic cassette tape players (eject and play functions only) intended for continuous play effect cassettes. Both units will plug into the Minisound I unit. All items are in very good condition and will power up. I did not get the chance to actually hear the unit since I did not wire it to a speaker, so I am selling these as-is (although I'm pretty sure it will work)."

Pacific Fast Mail Sound System 2

via swissdoc: "I came across this strange device called Pacific Fast Mail Sound System II, which is based around endless tapes and is intended to emulate the sounds of railroads.

Here is the old catalog from 1970 assuming they had one released per year...

Looks like they had a full analog synthesis engine in place before (no
tapes then)
