Electric train sound

Why does it make that sound?

[@Cosmos_Beatz]

man, i just love that idle humming sound on electric trains

[@nbauers]

You can hear the motor power switching circuits. To avoid wheel spin, excessive current in the motors and toppled grannies, the power has to be increased gradually. As the pitch increases, so does the motor current. The current is pulsed on and off at a high rate. As the pitch rises, the on-time increases and so does the motor power.

[@gaminghub8108]

Eventually it will give constant power which sounds low pitched

[@gamingultrabeastx5333]

And here you learn from youtube!

[@predatortheme]

Its actually the igbt inverters

[@MrBnsftrain]

Electric trains sound so cool when they leave the station!

[@muhammadchalidafin5644]

And diesel train sound.......hmmmmmm not really cool if leave the station 😐

[@MrBlueRBLX]

Yeah! H sets (Sydney Trains OSCar) have a lovely sound when departing.

[@Probably_something]

sounded like a BR Electrostar (377, 387, 379 etc yk ?)

[@arjunsridhar5974]

Exactly

[@SubiDriver17]

Ah yes, the RABe 514 acceleration is a sound I never forget:)

[@policecapture2046]

i like thomas the train

[@SamT]

It sounds like an electrostar on drugs lmao

[@Nice_Person7379]

Yep

[@diyaaldeen1097]

There is also a bit of LU 2009 stock in there(edit) the LU 2009 stock is not part of the electrostar family, its part of the movia family

[@PaulsDMVRailroadsandAviation]

The electric motors have these things called "inverters" which switch the current's flowing direction. These are alternating current (AC) motors; direct current (DC) motors don't usually have inverters

[@crazyboutferrets]

Dounds like the myc r142

[@teletubbyboi4207]

Bro has a death wish

[@Isaac2012YT]

I love that noice

[@JansArchiveActual]

It sounds like the Impuls train but wayyy higher in tone.

[@jennybecerra1104]

Cool

[@BusTransportvideos]

Sounds like Copenhagen metro

[@noahdemoliner7412]

its swiss

[@tacticoolkiddo9487]

@@noahdemoliner7412 yes true

[@SomeRandomPiggo]

This! Was there a few weeks ago and this sounds very similar

[@benjaminbonelli9335]

The green line of the MBTA has this sound it sounds low pitch

[@kdlehel]

asincronious motors sound accelerating.

[@adrianaadriana318]

what location is it

[@tacticoolkiddo9487]

SBB SWISS TRAIN

[@Great_WesternTVFan]

What was train called?

[@hiimjacobifyoudontmindchec5180]

shepard

[@sansoveio91]

It´s an IGBT Electric engine and this same engine is slowly carrying the energy to be able to take advantage of it better!
