When a voyager is at a station, during the process of the doors closing the engine revvs up? Does anyone know the reason for this?

Ok thanks
Didnt think closing the doors would require that much power!
So is this something that the driver is in control of or does it do it automatically when the doors start to close? Also when say stood at a signal, will the train do the same thing?
It is to get the engines up to speed ready for the higher electrical output needed for acceleration on departure - so this happens as the doors are closing, but it is really just a coincidence, two separate things are happening together.
Total and complete train spotter type rubbish !
The engine speed will stay at low idle (994 rpm) until the driver moves the master switch to direction, if the master switch is in direction with the doors enabled then the engines will stay at low idle, as soon as the doors are closed and interlock is achieved and provided the master switch is still in direction the idling speed will increase to 1144 rpm.
On VT the instruction is to keep the master switch in neutral until interlock is achieved and the right away given.
Love the sound Voyagers make when they depart. Really sounds like they are going to get you somewhere fast
I can hear a voyager from a mile away, they're very loud. Sometimes I can't tell whether they're stationary or departing, because of the loudness. Great engine though

xctoon is right. I thought voyagers were diesel and not diesel electric therefore you don't need to generate a higher electrical output.
Diesel engine is linked to a carden shaft which joins to a gearbox thus delivering tractive effort through the powered wheelsets.
They sound good though.
Great engine ?
They leak oil and coolant everywhere. Throw huge amounts of oil out of the breather and run so hot they rack the power back to cool off.
I disagree.......Not one of Cummins best.
No, they're DEMU's. Otherwise the plan to fit them with panto cars would be a waste of time.
...Arguably...They sound good though.
When passengers are required to sit directly above the engines, I don't feel that this is something that should be aimed for - The quieter the better: Locos are different, they keep all the noise in one self contained unit at the end of the train, for enthusiasts delectation onlyLoudest DMU I've heard though
(Although more accurately, aren't they derived in some way from marine practice?)

Jumped up bus engines with ideas above their station in life, in my opinion (Although more accurately, aren't they derived in some way from marine practice?)

That's true, but I am unsure if the Cummins engines also follow a similar lineage. Possibly not, and my "jumped up bus engine" analogy might remain more accurateI thought that was the MTUs running around in HSTs?
Compared to 180s, which utilise the same engine, the Voyager engine noise is intrusively loud within the passenger saloon IMO.As for voyager's engines, they're not actually that loud inside, or at least I don't think so
