Dodgey sounding 465917!

[P156KWJ]

http://uk.youtube.com/watch?v=KJD-5gZasTM the traction motors sound really messed up on this! Does anyone know what may have caused it?

 

[Jordy]

As said in the comments its just wheelslip!

 

[466.networkers]

I can confirm that the traction motors on Networkers sound exactly like that in the wet and/or when there is a bit of wheelslip.
Nothing to worry about at all.

 

[JoshW1992]

I think you are probably right guys. It was me that actually filmed that video, and at the time it didnt sound like wheelslip, as we were being thrown out of our seats almost. However, the weather was bad, so it was probably wheelslip, of a major kind. :roll:

 

[westcoaster]

just the wsp kicking in during acceleration, the jolt will come from where the wsp cuts power to the motors. then power will come back, if the unit was in multiple then the jult will come from the other powered unit pushing or pulling the unit you were on.

(wsp = wheel slide protection)

I have already said this isn't dodgy sounding motors!

But if you want hear dodgy units...

http://uk.youtube.com/watch?v=9K9JJlVu7Xw&feature=related the first 171 sounds a bit... not normal....

 

[JoshW1992]

Ah right, westcoaster. The unit was on its own, just 465917, so there may be other reasons for the jolt, but you know more than me, so I wont try and think of them. hehe
Thanks for the info :grin:

jolt could have from taking power while going through a gap in the 3rd rail, but im 100% its the wsp cutting power to the motors

 

[JoshW1992]

Yeah, you have to be right.

 

[Phoenix]

Is this your own video because if it is man that made me laugh *spoon*.

Do Networkers have WSP?

Do 319s have WSP?

 

[JoshW1992]

Yeah, its my video, and it is me speaking. :grin:

I have no idea....

ummmmmmmm yes to both.

That vid of the 171, there's nothing wrong with it, that's normal of Turbostars, as I heard that on FSR 170s when I was living up in Scotland. It's a fan unit of some sort I think, either to do with the engine cooling, or for the airconditioning/heating.

 

[Jordy]

Yeh just sounds like the cooling fan going slightly mad

 

[Turbostar]

One of the characteristics of the good old Turbostar, & like Jordy says, they can get a bit noisy at times!

Yes but there must be a reason I.E the engine being too hot.

 

[Turbostar]

Not necessarily, like I said, the FSR 170s do it all the time. It don't run all the time, same principle as car engine, comes on when needed.

I mean about the cooling fans to be working overtime...

 

[Turbostar]

They're not working overtime, that's normal! I already said. :roll:

Ok, have a look at this for example:

[hairyhandedfool]

319s do have Wheel Slip Protection and Sanders.

Wheel SLIP is when accelerating.
Wheel SLIDE is when braking.

 

[Royston Vasey]

Have experienced this quite often on 365s on wet days (though not realised what it was before) but nowhere near as severe, it just feels and sounds like the driver has eased off and brought back the power gently. How come there's so much difference on this particular 465?

 

[ungreat]

It is likely to be wheelslip..I drive 365's and they do just the same thing..when they slip,the power cuts automatically and then re-engages to minimise the slip.It also may be another common(well,certainly with our 365's)problem in that the unit might have a power problem which makes the motors overload briefly when taking power.This gives a similar feeling to slipping,but with a bit more of a lurch from the unit.

 

[AlexS]

Exactly the same with the 323s too - they have the wheelflats to prove it!

At worst, that sounds like a worn bearing in the fan. nothing major.

Oh ok, cheers.

 

[adamp]

Can this jolting happen on 321's ?
Was a very wet day and travelling to Doncaster from Leeds...
As we were setting off, more often than not it would speed up, a huge clunk. then speed up again abit longer...then clunk.
Is that the WSP?

 

[class 313]

It can happen on any unit.

 

[driver9000]

with regards the radiator fans, there is a feature on the Pacer & Sprinter units whereby if an engine reverts to idle and wont power the fitter can wind something on the radiator (cant think what its called off the top of my head) in and this will make the fan run continuosly and this makes power return to the engine. Ive called fitters out to 14x & 15x (mostly 142s!) with an engine at idle and they have done this and its solved the problem....

all units have the WSP (Wheel Slip) device fitted, diesels will idle the engine and light the train transmission fault light when the speed probes detect a difference of 7mph (if I remember rightly from driving school) between axles, they will cause the power dip, returning power when the difference comes back within tolernace. The driver can leave the power controller open and the train will do the work, unless the train is struggling then it can be done by hand notching

And locos

Skodas are high quality engines - 10 minutes Watford Jn to Watford Tunnel on 1S25 one autumn....
