Weird noise on the M7A

Post by lilbluefoxie » Sun Oct 30, 2011 8:01 pm

Earlier while I was riding up to Croton Harmon I noticed this wierd sound that went over the PA system, sounds like something out of like star wars or star trek, its defenately not someones phone cuz Ive heard it before every other time i've been on an M7A, it is always followed by the usual ding dong sound.

Is it a 3-tone sound? That's something having to do with the announcement system booting up (I think), I've heard it on many LIRR M7's just before or just after leaving the first stop.

its not the propulsion noise, that I know, its this wierd techno type sound, ive been on the LIRR tons of times on all 12 branches and I never heard it on any M7 that I have been on.

It's the chime function on the PA system. It's completely useless except to annoy crew and passenger alike. Occasionally engineers will use it crossing over an interlocking letting us know to hang on or there's a wheel chair on the platform, or "man on the roof". But 97.6% of the time it's by accident or a bad PA panel.
Hurry up and wait at the signal!

apparently the Long Island Railroad M7s have it too, as I heard it go off on the Brooklyn branch train I was on today.

I've heard something that was, I think, an 8-note sequence at the end of a run on moth LIRR & MNCR. Once while waiting to depart Southeast I could have sworn I heard a "Thank You for Riding Metro North Railroad" message that I had never heard before either...

No, that's something else. That is the start up message for the ASI; happens when there is a error in the system and it restarts itself.

Kind of like how when you reset your computer, it makes the start up noise (i.e the Windows start up noise).
