Wait, It’s also The Same Brakes and A bit of Acceleration And Deacceleration Of the line 3 Of Milano (or Milan) Metro,Italy

I don't think the second one is bombardier. There are loads of bombardier in the UK, they are very distinctive. Are you familiar with train VF drives. I am trying to put some names to commonly heard drives. With the Nuremberg DT3 trains, this sounds very different to the Siemens drives that I know of. Siemens usually has a very distinctive hill start feature, where it puts 100% power on for 1 second when it first starts, then lowers down to the amount needed to hold the train, then powers back up as the train speeds up. Like on UK Class 700 and Oslo metro. A couple of others that I am trying to put a name to is the 323 VF drive. It has no pure PWM mode, it starts straight into pattern pulsing. And the Croydon tram VF drive. Extremely distinctive.

I checked for the DT3, class 323 and CR4000 Croydon Tram The DT3 says that it's a three-phase asynchronous Siemens IGBT. The 323 class says it has 4 Holec DMKT 52/54 traction motors The CR4000 has Kiepe Electric GTO drives

@@anfsabc_busotto The trams in the end sounds like Bombardier VF drives, similar to the Frankfurt Am Main trams.

The tram is a CAF Urbos (1st series) but i can't really tell what VF brand it has, even though it's a clear IGBT

The inverters on the 500 and 550 trains are the same (ABB), but in the 600, 900 and 950 trains the inverters are from CAF

The pitch gets lower instead of higher while accelerating, strange

dykodesigns2yt well it works pretty well and never breaks down. So maybe it’s better to have a more “hiddious” tram that does its job and will always arrive rather than one that’s more “futuristic looking” but has a high chance of letting you down.

Also reminds me of the Class 323 with the weird traction motor sound lol

Doesn't sound like any of those trains to me

Beno True.

Euskotren es asi en todos lados 😂😂

ASY Yp. Does sound just like the Class 365, Class 465 & Class 466 Networkers.

@@AndrewG1989 no it doesn't. Not even the same manufacturer

Thanks

I love lift surfing

Is Bilbao not BillBow XDD

I know. Things in casual communications are often mis-spelt for comic effect or to reflect pronunciation or mis-pronunciation.

@@trainluvr Ye i know but that made me laugh a lot (cause im from BillBow😂😂).

It's normal, as caf is a Basque company and Bilbao is at the Basque country it's like "homemade" trains

Im guessing ac and dc operation. The higher pitched start is ac I think and the lower start is dc

As far as I can tell, it is the same VF drive, but the pulsing frequency is set higher on some trains.

DS Intel, the metro doesn't use different power types. If it did, the AC or DC does not make a difference to the sound, other than maybe a slight 50hz hum in the bridge rectifier. Often on dual voltage trains, the AC is at a higher voltage. This is then reduced down to the trains voltage, but this means it has more current. If the VF drive takes advantage of the more available power, then the pulsing frequency is sometimes lowered to stop the transistors overheating.

Ok

johno aka some fat guy from Yorkshire for starters it’s a different series of trains, commissioned and built around 2010 rather than the other ones which are from the 90s.

I have surfed over 200 lifts in Germany

Beno I found a glass lift a Schindler lift at reading museum.
