Wanna know why it makes that very distinctive sound? A lot of people may think the changes of sounds are of the train changing gear, which isn't true. So many train enthusiasts will tell you that it's because it uses motors from Westinghouse/AEG/Adtranz (the company who supplied the motors for this train) and mostly "GTO-VVVF inverters". The GTO is actually the name of the transistor/thyristor technology used, but not all sounds relate to the transistor technology. The sound you hear is caused by the VVVF drive pulsing out an artificial AC wave from a DC supply. And again, it's not the train changing gear, it's caused by a byproduct of how the software has been programmed. When we use pulse-width modulation with AC motors in 3-phase configurations, we require 2 sets of transistors for both positive and negative, and since we have 3 phases it means we need a total of 6 transistors. GTO thyristors (as our so called transistors) can only pulse at about 400 times a second. This means when we reach a certain speed, we need to cut out some pulses to stop the transistors being overloaded. And since the pulsing is what causes the sound, each time we cut out some pulses the sound goes back down. Then we have it; the distinctive sounds of the TTC T1 train!
In 8 years from now, these trains will be fully replaced by the current Toronto Rocket trains and the future subway trains that will be introduced in 2026.
Great video miss the t1 with the old chimes
Thanks!
Transit Miranda do you seen 5166-5167?
They both sound like the First the notes from Sesame Street
Now in 2022 I miss when the chimes were earrape
I keep seeing the 5336 is always leading everytime i go to the subway station
Cool. I seen all sets as leading cars anyday.

Amazing
can you do a vid of the line 3 trains?
Awesome video mate man god bless and family as well ♥ :-) Love Hearts
Thx!
Transit Miranda your welcome love anymore Kipling Station video
@@FamilyGuyandWonderGarbo8448 I didn't planned on going to Kipling station yet.
@Transit Miranda Okay Miranda and have a nice beautiful day ♥
@@transitmiranda I haven't*
Awesome 👌🏼
Thx
i have to take to bloor-yonge station
Nice!
Is it just me? Or does the door chime sound like the First 3 notes of Sesame Street
They only have these trains in line 2 now. I just hope they won’t go away soon

@@transitmiranda in 2030 they are gone
Rip looking out the front window
Can't the (totally not) idiots just modify a toronto rocket to have a front window for passenger
Like it's that easy just cut the wall infront and remove thingys
this is line 2 ttc
Yes
