Artemis's project to convert DVT to use hydraulic energy storage

[D365]

What happened to the facebook page that was shared this week?

The trial was due to start in December, but we havnt heard any talk about its arrival yet in Chiltern land. As far as i know it will be attatched to the back of one of our sets and will assist with acceleration from stations thereby using less energy to move the train from a stand.

Short update on this posted on WNXX today:

The creation of 19001 continues to progress at Bo'ness. The horn grill has been replaced with a new 'Artemis' laser cut horn grille, Artemis vinyls have been affixed and the newly created second cab is being fitted out. The 'locomotive' will be on display at the forthcoming Bo'ness Railway Diesel Gala

The mentioned gala is on the 29th of December.

Does anyone have any photos of the gala?

Shame the cab looks... meh...

It's not a finished product is it? That certainly won't do for anything other than shunting.

Is it not also the case that this is just a prototype for the traction package? The Mk3 DVT is a readily available empty shell ready to be fitted with whatever kit someone wants. Once the systems are perfected, they can be fitted to other types of trains for production use.

This project had completely passed me by until now, but...

A YouTube vid has been uploaded ('ecksfilesbonyuk8' channel, sorry can't post links on this phone!!), 23 May 2018, showing progress of work being undertaken on this project on DVT 82113, in the premises of SRPS at Bo'ness, on behalf of Artemis Intelligent Power.

Mentions JCB power plant and hydraulic accumulators to store and release energy from braking to boost acceleration, and being a trial/test-bed funded by RSSB...

Worth a look, and once again apologies for not being able to share YouTube link..!

What an interesting video. Id be curious as to the apparent lack of friction braking on the lead bogie (reduced brake force especially with all of the weight that has been added. Also from one of the interior shots towards the sharp end, it appears the cab air conditioning unit has been removed, whether this is permanent or has it been removed for repair/ reconditioning....

All the same, very interesting, but the thread title does need to be changed to remove Chiltern as its not their project.

Wow, to go from no information to all that is a lot in one go! The progress seems to have been pretty rapid. I'm reminded of the Parry energy storage system, which is mechanical flywheel storage rather than hydraulic storage. Does anybody know how the storage is intended to be captured/used?

The L plate on the blunt end was a nice touch as well.

London transport did a similar experiment with a Daimler fleetline bus. I seem to remember the efficiency of the hydraulic drive system was much inferior to conventional even with accumulator energy storage.

This sounds most interesting.
In view of the recent and ongoing advances in battery and supercapacitor technology, I find it rather surprising that a pressure based, rather than electrically based energy storage system is being trialled.
With the delays to electrification, diesel power is going to be around for decades yet so improving efficiency is to be commended.

it is an interesting experiment. Those storage tanks look awesome. I'll be looking forward to the results and hope it's a success story and can be rolled out.

Pressure based storage might be cheaper (lithium-ion batteries are quite expensive), but I don't actually have any numbers on this. Perhaps safety is also a factor - a crash involving a large lithium-ion battery wouldn't be pretty.

Well, the project/trial is being sponsored/funded by the Rail Safety and Standards Board.. so there may be something in this suggestion..

Wasn't previously aware of RSSB involving itself in trials such as this..

Are there any other comparable examples..?

 

[D60]

Turns out in addition to being concerned with safety and standards, RSSB also has a 'Sustainable Rail Programme', which among its goals is included "meeting rail's carbon ambitions"...

One of the captions in the video linked to above suggests that this is a test-bed to test the feasibility of this technology for use in a future generation of DMUs.. (specifically DMUs rather than SPMUs or whatever..)

(specifically DMUs rather than SPMUs or whatever..)

How many abbreviations do we have for battery trains now then?

Don't know.

Seem to recall seeing that recent franchise tenders have stipulated a requirement for provision of either 'self-powered' or 'independently powered multiple units, or words to that effect..? Rather than simply DMUs..?

But anyway, what I was pointing towards was that one of the captions in the video referred to DMUs specifically rather than any other form of traction or propulsion. (No idea how authoritative the captioning of the video is!)

Hope that is a helpful reply..!

 

[gingertom]

what isn't clear from the video is how the machine will be used. Does anyone on here know if the small diesel be used to pressurise the tanks so it can propel itself and payload, or is the kinetic energy of the moving train to be (partially) recovered during braking?

Probably mostly the later and occasional the former. Using the JCB engine to run an air compressor would also be useful which it probably needs to but isn't stated.

The blunt end is the stuff of nightmares.

I'm even more intrigued about it all now, even if the blunt end has a cyclops thing going on. I'm guessing the corridor was removed because there's no usable room left inside anymore (so what becomes of that space, operationally? Where do the bikes/bags/etc go?), but also I imagine it was a lot cheaper or easier for the purposes of the trial to just do that than try and fit it in alongside the existing corridor. Then again I don't see why knocking a small window in a small control panel below wouldn't be doable. But then if there's no reason to go in the DVT anymore, a corridor is pretty much redundant anyway. I'd presume a production model would have a more refined layout, more internal fitting, and retain some space for the guard, etc. It's basically just an engine plopped in the middle right now.

Artemis's website is vague on the technology. They mention their fancy pump they have, which does seem to be their main product, so it sounds like a system of two halves. One half is their standard setup, hydraulic pump and a diesel engine to drive it, but the other half is the accumulator powered by braking. I can only assume they want to test a few things here, like how efficient their pump is driving a train from a relatively small diesel engine, or at least giving a little extra push. They've been testing their pumps as a drop-in replacement on Scotrail's 170s to run the AC and save fuel, so this is a rather big step up. Then there's also the braking accumulator, which seems to be the rationale of the testing. I think they're just seeing what their tech can do, really.

You Tube now has a video of the DVT making a test run up and down the yard under its own power at the Bo'ness and Kinneil. A caption states that it was filmed on 1st August. I can't post a link just now but a search using "Artemis test run" ought to find it.

Quite.

"Cyclops" would be an appropriate nickname... Though form is secondary to function of course!

Minion is another name mentioned.....

Hey a slight idea for these?

could these be used on the Fife circle line if scotrail replace their MK2's with redundant MK3's? so maybe like, Artemis - 5 MK3's - 68 or 73/9

don't see why not. Do remember this is an experimental project to prove the technology. If it does work as predicted and (most important) is financially viable then we could see quite a few of these in service somewhere. Chiltern comes to mind.
