chiltern Mk3 DVT generator vans.

[t_star2001uk]

The first of the DVT generator conversions is on site at Wembley. 82304 was worked from Loughborogh yesterday. I will try and get some pictures both interior and exterior tomorrow ....

What is the livery on 82304?

 

[MK Tom]

It's still in W&S colours. See http://www.flickr.com/photos/36593372@N04/6519851423/

I suppose this substantially reduces the space inside the DVT for storage of baggage and so on? Not that this is used very often anyway (last time I saw a DVT being used for that was at Edinburgh on a London train)

 

[t_star2001uk]

Looks like one of the Wembley fitters beat me too it....

 

[Schnellzug]

gnerator vans? Oh, I see, looking at the picture, it's kind of like an APU on a plane.

Incidentally, I seem to remember that Modern Railways once speculated, when the WCML upgrade* was first mooted**, whether it might be feasible to turn the DVTs into power cars by putting in a diesel generator and putting on new bogies with traction motors. I wonder if it would in fact be possible? Could it take the weight of say an MTU 4000 engine?

Interesting news. Do you know whether the generators will run all the time to replace HEP from the locomotives, or just during station layovers?

It appears, from the description with the photo that's linked to above, that they intend to use them to power the train supply during layovers while the train engine is shut down, like an APU on a plane while it's on the ground.

Station layovers and stabling only, the class 67 will still have the ETH on whilst moving with passengers on board.

Its also been fitted with train door controls for use with the power door fitted MkIIIs.

Do those differ from the controls fitted from new? They had control similar to the Mk4s.

 

[t_star2001uk]

I took some pictures of 82304 today, both exterior and interior. I will be posting them later when. I get home...

Ok here we go for some pictures of 82304...

As you can see there are quite a few modificattions that have been made. The brake distributor has now been moved from the underframe to just behind the TDM cabinet. There is also a roof mounted exhaust positioned just behind the air intake grills.

Tidy job, I've heard Network Rail were watching this project with interest for their fleet. DVT's are rumoured to be on their way to the test fleet and will need generators fitting.

 

[HSTEd]

That looks like quite a good job although I think it would be nicer if the gaps in the intake slats were a bit smaller rather than appearing as gaping holes in the sides.

Do we have anything on the DVT's ETS index?

 

[swtandgw]

Its also been fitted with train door controls for use with the power door fitted MkIIIs.

Does that mean that some MK3s are going to get plug doors soon?

 

[MCR247]

Chiltern are fitting their sets with it, with 1 or 2 sets at Doncaster having it done now

 

[jonhewes]

Good pictures in an interesting thread!

Will the 67s working the power door sets need retrofitting with door controls? If so, will this preclude other 67s (eg 67018) working for Chiltern?

 

[Schnellzug]

They seem to have made quite a neat job. Who knows, perhaps this could be extended to other types of stock to obviate* the need for ETS locos, or as a kind of emergency backup for when trains have to diverted away from the wires.

Thats an interesting possibility. I wonder what the ETS index is, and whether such a DVT would be able to deal with a East Coast or East Anglia rake, being significantly longer than a Chiltern rake.

Earlier this year when I took a bike on EC, the space in their DVT's seemed to be pretty well used between luggage stowage, bikes and supplies.

The intakes on the side are that size for a reason. Just think you have a large V6 marine diesel sitting in an enclosed space with no air flow, but just to make matters worse it's then enclosed in an acoustic casing. So unfortunatly the intakes do have to be that big...

 

[Schnellzug]

What engine do they use in it?

 

[t_star2001uk]

I beleive its a Volvo V6 marine diesel. But i'LLC see if i can find some specs today.

A marine diesel? I'd be surprised if platforms on the CML start sounding like marinas once the generator is on!

 

[Drimnagh Road]

Could have had the engines out of our mk3 generator vans, they were all fitted with brand new Cummins LTA 10G3t engines back in 2005, output 202kw at 1500rpm. They made a lovely sound.

Might be a little overpowered for what Chiltern need them for though.

 

[t_star2001uk]

So I'm led to believe set AL04 should be with us in January ..

That would be an ETS index of around 40 right?

Well based on the fact that Cl89s had an ETS index around ninety and can apparently handle a 9 coach rake, it might not be that excessive, especially with all the extra electronics we have in trains these days, and the power sockets.

 

[t_star2001uk]

The generator is powered by a 6 cylinder in line Volvo Penta engine which has an output of 442hp at 1500 rpm. This is coupled to a 3 phase alternator and a mechanically driven compressor.

When you say "set AL04", do you mean a complete set of power-door Mk3s?

 

[t_star2001uk]

That's the one. Set AL04 was the first silver set to be sent to Doncaster for the power doors to be fitted. Set AL01 is also at Doncaster. 82304 is still under test at Wembley and should be ready to go with a loco to pick up set AL04.
