Re-engineered Class 73

DBS tested a modified 92 (92031) that could run at 100 mph, modified ets. Not sure how we'll it worked but with plenty of 90's about and the up coming contract renewal it was shelved. Very possible for Gbrf to do the same.

Any nicknames for these little beasties yet? ED doesn't quite seem appropriate anymore?

 

I think they have the look of a Cyberman? Any thoughts?

 

ED-209? We watched the new Robocop film the other night, can't think of anything else for them. They do seem to be a long time appearing. I wonder how long it will be before they are in service (and will the model appear before they do?)

I'm a tad baffled about these, all the information that I have found about these locos is that they have two engines fitted. Which seams an odd design feature, considering the twin engined locomotives in the past where deemed nonstandard by the BRB and withdraw from service.

 

Could someone enlightening me as to where the radiators and the engines are located.

 

Thank you.

The Network Rail locos have two engines fitted - only fired up as required. It's a tie-in with the National Railway Equipment Corporation of the US - they have experience of "gen-set" technology using more than one diesel loco.

 

The Brush/GBRf rebuilds have only one diesel engine.

 

Both variants have substantial bodyside modifications to incorporate new cooler groups - as yet, only the NwR 73/9's have showed themselves to the public in any detail.

Bear in mind that modern engines pack far more power into a smaller physical size than the 1960's built EE 4SRKT which is why they are now supposedly rated at 1600hp (or so) under diesel mode, when compared to the original 600hp.

 

Cheers,

So that means that, if the electrics are much the same as before, the continuous power rating is now the same for both diesel and electric power.

If that is true, they should still have more 'short-term burst' power as a straight electric if needed.

 

I haven't entirely kept up with this thread so if I have missed or duplicated something here, my apologies. :)

 

It is nice to see the EDs (or whatever new nickname they receive) being refurbished and given new leases of life. I am sometimes surprised to think no other such versatile machines have come to fruition (including the class 74s which weren't as universally available). They really were/are 'go anywhere, do anything' machines.

Or you could say that they are anytime, anyplace, anywhere machines, so we'll call them Martini's?   :)

Both versions will have AC alternators instead of the original DC generators, so needing at least some modification to the electrical traction systems.

 

In the case of the NwR/NREC 73's, the electrical traction systems are most certainly completely new, so it'd be interesting to see if they still have an extra "boost" when needed. I would expect the GBRf stuff to have new traction packages as well, but I'm not sure.

And along came the rather smart looking GBRF version.

Of the two, I rather prefer the GBRF version to the rather messy looking RVEL conversion - the bodyside looks like a 73 as does the slightly more modern looking face, which retains it's SR equipment while gaining a new Multi Working Socket and WIPACs - The RVEL one in this respect looks rather ugly given it's cleaner face and removal of everything but WIPACs.

As someone who had done sub con work for RVEL all I can say that they over do everything and thats why everything they do takes so long

It's what we've got used to.

 

If the 73 originally had a clean "face" and all the SR high level stuff was then added, then we'd only be complaining at that!

 

In much the same way that 57/3's have received Dellner couplers to muck up the front view.

Cracking photos on Flickr of 73962, shows the details more. I am going to be controversial and say I think RVELs 73/9 looks more adventerous in re-build stakes. Plus the twin engines in the RVEL version make the Climate Scientist in me happier for saving Diesel. But still, I shall have a model of the GBRf Wabtec 73/9. I quite like the plain livery, but maybe they can put the Europorte red and orange curves?

 

Though I am surprised the Wabtec 73/9s have had such extensive re-build as the RVEL 73/9s as 73964 shows below.

Grabbed a few piccies of 73952 at Kidderminster whilst on the SVR today. Will upload when I'm back home. My phone is not co-operating at the moment...

73966 is now on it's way up the ECML to Craigentinny, accompanied by 66732, currently running 111mins late, so getting into character for the sleeper services by the looks of things.
