Why do Class 444's and 450's "squeak"

[Ascot]

Heard this a while back. Basically they installed Jerry, now Jerry is a little mouse situated between the bogies so every time the shaft goes round it makes him alert, reason they installed this was to frighten the chavs away at Stechford as they would be scared as somethings living under it. However to keep the mouse awake they had to install slam doors so they would hear a loud bang and sometimes their tail would get caught and end up in notch 4.

323s now there just clapped out, since when do we get priority trains or nice 10 car locals stopping everywhere like the south east? We get stuck with bangors and mash units with 3 cars if your lucky!!

£56 though for a monthly season ticket :razz:

EDIT: As for the interlock AFAIK there New St proof (aka idiot locked) so you can turn your little key till the cows come home but that panel won't light up until below 3mph (but looking here they changed it??) and even better it's colour coordinated so the two red ones light up when you got to open them, they knock off when the doors open and the little blue one lights up

'tis set to 4mph on the SWT Desiro's, there is a manual override panel for the controls to come on in the cab if it is required (mainly for when the bell is required for emergency stop).

So by the time you see someone jumping out, you have to find the override, flick it, then go to the panels and push it on SWTs by which time your a few miles gone. Or better to make it clearer as there's like 4? bell buttons on the cab? (2x cab DOO ones and 2x Cab door walls or there one by the uncouple buttons and only one DOO button?)

360s also make the same squeek... its quite handly to know when I'm pulling off so I can get excited about getting home sooner

The override are the buttons in the cab ...

Basically it's just the Door Rel's that knock out in cab. Locals have something fancy built in them that knocks the whole lot.

 

[Tom]

The PA should still work in the local door controls ...

I thought the panel needed to be activated for that.....

 

[Ascot]

There's a video posted on here a while back about some kids playing with the SWT announcement, was just trying to look for it but couldn't find it. There's nothing to the PA anyway Tom just a few wires, not interlocking..

You did say the entire local door controls went off ...

If I'm not mistaken, the PA is in the local door control panel.

Door controls yes, PA is in a separate partition below the door controls, also be pretty pointless to install idiot locks on the PA for 4mph though.

New Sound... (clicky)

That happens on some 450's... when I first heard the new sound I thought it was broken!

 

[me123]

Sounds like a UFO!

 

[class 313]

The 332s make a smooth eeeeeeeEEEEEEEEEEEEEEEEEEEEEEE sound from all traction packs (when working!)

332s just screech!

New Sound... (clicky)

I don't notice anything different to that clip to the older sounds

 

[Tom]

You're deaf then.

Notice the lower warble quickly fading into the high warble?

 

[Juniper Driver]

The noise did seem to change on them a few months back, can't describe exactly what the difference is, but it is noticeable to people like me who have to travel on the wretched things every day.

The noise has changed.It used to be the same noise from pulling away to motoring but now when the train pulls away there is a different sound which changes into the normal sound just after it gets moving.I noticed this and also another thing is it seemed to happen overnight throught out the whole class.

 

[kestrel]

Im sure the 332s also make this sound too but more of a EEEEEEEEEEEEEEEEEEEEEEE sound rather than it alternating.

driving both 360's and 332's today

Its the IGBT's as said earlier, the frequency change is more noticable on the 332 than the 360

 

[Juniper Driver]

Im driving a Juniper 458 tommorow for the first time since 18 October.No desiro's for me today methinx.I think it's 455s.

Certainly didn't - happened after a certain exam for each unit, can't recall which one though. Involved upgrading the software in the unit so done after a particular exam at Northam...

 

[Juniper Driver]

Thanx.I think the software upgrades have improved the units.

There is a few drivers at Waterloo who moan at the "delay" between when they move the brake handle and when the brakes actually apply.A second or perhaps less delay.I keep saying to them that I dont have problems with them and usually do good confident stops rolling up to the stop blocks unlike the early days on them.

Im sure that they are more improved to what they were like three and a half years ago as well as us all being inexperienced in driving the units and compensating for said delay at the time.

Riots with Walsalls at the moment 153+170 combos as the brake kicks in at different times on each unit so stopping is a bit of a guess ! Farce !

Went on 1 without it's mods yesterday! 019 IIRC

I remember working the 57/63 slam door combos.Usually the 57s used to push the 63s if they were at the back.
