Question regarding turning Class 68 engines off

[putabidin]

Is there any way that the engine can be switched off from the cabin of the DVT mk3 at the other end?

 

[t_star2001uk]

Yes. There is an button marked Engine Stop/ Pan Down in the DVT Cab..

 

[putabidin]

From my flat overlooking Marylebone Station I see the drivers walking the length of the Class 68 to turn the engine off on arrival. Why do they do that if it can be turned off from the DVT? Do they need the exercise?

To dispose of the loco in the correct manner the driver has to walk to the loco, turn of the ETS, apply the parking brake, Shut down the loco and turn the Mode Switch to OFF. If the Genset is to be used the ETS Isolation switch must be turned to off as well,

Does anyone have a definitive answer to this question, please.

If a Class 68 is shut down at the end of a journey from Birmingham to London and is due to leave London 30 minutes later, how long before departure does it need to be started up again in order to carry out necessary safety checks and build up brake pressure?
Forget any need for the provision of "hotel" services for embarking passengers.

I can't answer for the Class 68s, but I have often heard the Class 218s of the German railways (DBAG) being started at Munich Hbf only a couple of minutes before the train departed. These are a much older design than the Class 68s.

(I used to live in Munich and have personal experience).

Theoretically it should be detailed in the Local Instructions in the Sectional Appendix, but I believe the relevant time is 10 minutes prior to departure.

I'm sure that's a 'how long's a piece of string' type question. While the safety checks will be pretty standard, each set will lose pressure at slightly different rates on different days.

Would it be possible (I imagine so unless regulations have changed, though it would be expensive) to reverse the rakes so that locos were at the London end, and install a system like that used for the thumpers at Victoria? By which I mean the exhaust ducts designed to pump diesel emissions out of the trainshed?

But why?

Can anyone verify this?

But why?

They may interfere with the lifestyles of people who live or work overlooking the open end of Marylebone?

 

[NickBucks]

Have you ever heard the noise a 68 makes when leaving Marylebone ? It is bad enough at the country end in the open. In the shed you would not be able to hear any announcements at all.

 

[KingDaveRa]

Quite a few times I've been in the car driving under a bridge along the Chiltern Mainline, and you KNOW when a 68 goes over. Those things are impressively loud.

ham and Shropshire first started the amount of complaints that we had from residents was amazing so they had to be then shut down when they arrived.

You make my point for me.

IMPRESSIVE to you, DEPRESSIVE to those living around Marylebone who have to listen to 4 hours of Class 68 idling between 7.30am and 6.30pm.

I'm researching the best outcome we can reasonably achieve in getting Chiltern to reduce this.

All help gratefully received.

So what's your agenda here?

Looks like we probably are one of the "I moved next to a railway and am complaining its noisy" type.

Live next to the railway and complain about the noise trains make.... Standard.

 

[CyrusWuff]

The irony is that using "compressor speed-up" on a DMU to build up air pressure because the unit's been shut down for an hour and restarted 10 minutes before departure in line with the usual noise reduction policy is potentially louder than a 68 at idle...though I have no empirical data to back that up.

There's a qualitative difference though between the comparatively high pitched sound of a DMU engine being run at high speed and the low, almost infrasonic rumble of a Class 68 at idle. You can feel it as much as you can hear it.

While I agree that the railway was there first, it's not unreasonable to seek a practicable way to ameliorate the nuisance.

It sounds like Chiltern already shut them down on arrival and fire them up shortly before departure. Not really sure what else the OP expects them to do...

Precisely, reversing the sets and installing some kind of extractors under the train shed would just serve to deafen the passengers and station staff.

PC time for a 68 hauled set is 17 mins in a platform
TC time for a 68 hauled set is 10 mins in a platform

I think, ultimately your barking up a dead end. Chiltern already have processes in place - which have been described to you in many threads - to abate noise to the minimum levels sustainable within their operational requirements. The only solutions that will provide a meaningful difference above and beyond what they do already are prohibitively expensive.

Bottom line, the railway is a business; not a charity. There is no obligation for them to spend vast sums of money to be a better neighbour to residents who knowingly chose to live adjacenct to a busy London terminus. Operational requirements; and therefore noise levels change over time - again there is no requirement for Chiltern to consult on that, just that they keep noise levels to the minimum sustainable within their operational requirements.

Whilst I don't question that noise is an issue, you may get more attention by (also) mentioning diesel exhaust ...

 

[najaB]

And that would be a perfectly acceptable answer: "We've looked at alternatives and unfortunately we haven't found one that is operationally feasible."

It's not good enough for the railway to say "We were here first, like it or lump it."

There's a qualitative difference though between the comparatively high pitched sound of a DMU engine being run at high speed and the low, almost infrasonic rumble of a Class 68 at idle. You can feel it as much as you can hear it.

The master of the infrasonic rumble was the Metro-Vic Co-Bo.

In Ladywell House Preston, we always knew when the late afternoon train to Barrow had arrived in Preston Station from the south, thanks to the throb in your ears.

Excuse my ignorance, but PC and TC times are...?
