Reving trains.

[43021HST]

Is it possible to rev a train? If so how do you do it?

 

[37401]

Throttle on then off, same as a car really...I think lol, I dont think you can rev units as much, locos im sure can be reved

 

[GB]

Stick it in neutral and apply power.

 

[GNERman]

yeah, reverser into neutral, brakes on and give her power, I did that to 37901 at neville hill...

I bet that was a hell of a rev!

Nah slug 6 is better, ruston engine

And why would anyone (other than a Jeremy Clarkson wannabee) want to?

 

[ralphchadkirk]

There are some instances where you would want to, but I can't recall them at the moment.

The sound was amazing, the clag was immense and the vibrations in the cab were big and unexpected...

Maybe, but this is the last Mirrlees engined Slug surviving, there are two Ruston Slugs in preservation...

to **** of punters and make them run works a treat usually
some units have a rev up button afaik - I'm aware of it on 170's anyhow

Most diesel units, certainly the sprinters and turbostars, have a compresser speed up switch. This is used to build up air in the main reservoir for brake release. If a unit spends a long time shut down, then air pressure can drop below the threshold for brake release (between 4.5 bar and 5.5 bar). So in the mornings, and if a unit has turned around after a long time, you'll hear them revving up to get pressure increase.

Heard it a few times, best thing is the passengers reactions "Its moving with the doors open"

 

[poshbakerloo]

the 153s rev real good!

 

[red circle]

If you opened the controller in EO on an un-refurbed '37 the engine ran up faster than the governor could catch it and the overspeed trip operated.This had to be reset and that lever had the strongest spring you could imagine behind it.

that's why they do it, i've noticed it on 158's and 185's at york station quite a lot, not knowing why though...

 

[SWT Driver]

Or on a 170 use the holding brake button on the PBC & put it into full power!

Used to do that to **** off the Totton Mafia!

There wouldn't be a reason to rev up an engine manually, it can be done but it is a pointless exercise unless like some you get off on the sound of a diesel engine screaming. I can't think of any driver who would rev up an engine for no reason.

The compressor speed up is a toggle switch to rev the engine on a unit to build up the air quicker, fyi you cannot get a brake release with the compressor speed up on, the have to switch it off to get the brake.

How about for ETH purposes ?

There is on an HST P/C.

 

[Vulcan]

Narrow gauge engines are easy to rev pointlessly, but when they are mostly fitted with low revving engines its neither interesting or good for them.

 

[ungreat]

And why would anyone (other than a Jeremy Clarkson wannabee) want to?

Freight trains often rev the engine to charge up the brakes on a string of wagons that are dead air wise quicker...I know,I used to do it lol

ah thats the one fella! lol I wondered what it was called doh!

I've seen a lot of units get revved up at Sheffield just after they've been started up, probably to warm the engine up. It can get very loud!

As explained above, to charge the air system.

Are you sure 170s have a speed up button? I only ask because 168s aren't fitted with one which is a pain in the a**e very often.

 

[feliner]

A class 66 will rev up on its own when the main air gets low, one can look a bit of a plonker approaching a red signal with the loco,revving away.

nah, I have to say, If I saw that id be impressed
