New electro-diesels for the UK?


Recommended Posts

While last mile diesel does add to cost and weight, I'm pretty confident it's cheaper than a specialised shunter's at every yard, remember especially that there are now very few large yards that could find full time use for one.

Remember too, the places that load from above, hoppers and containers in particular

 

Not to mention in todays system, you may be relying on (and paying for) somebody elses shunter and crew to do your shunt moves for you...

 

Ref 86/87 - they also wouldn't offer the same capability...

The EDL was a good idea at the time, and its continued popularity as a concept indicates it's a good idea now. As long as they're not built by the people who did the Class 74....

 

The 73 was designed/built as an ED, the 74 was re-hash of an existing electric.

I've seen the two 73's stripped down inside RVEL at Derby for NR. And I mean stripped down! The only paint that was surviving was on the cab doors. They will essentially be a new loco, with significant parts of the steel body replaced and pretty much just the bogies surviving. I believe this route has been taken for the test bed pair because the 73 is an existing design and won't need as much certification as a 100% brand new locomotive.

 

 

Cheers,

Mick

There's another one being done at Brush for GBRf, isn't there? Perhaps this might be a way of using that line of apparently-gutted Class 92s at Coquelles..

Yes there is, however in true railway tradition its rebuild differs significantly from that being undertaken at Derby with a completely different engine configuration. I believe though that the end results are broadly supposed to be the same regarding tractive output.

 

The thing about the 73s is Network Rail has realised that there are some bits of the network that are so restricted that only 73s and 31s will fit. Equally some freight operators have realised that if they had a bit more 'grunt' under diesel then the 73s would make an ideal 'super shunter'  - Hence the rebuilds under way now.

RVEL are rebuilding two 73's for Network Rail. A pair of Cummins QSK19 engines will be fitted using Nforce multi engine control systems from the National Railway Equipment Corp - they specialise in gen-set locos.

 

Brush are rebuilding a few (four?) for GBRf using a single Caterpillar (I think) diesel engine.

From memory GBRFs pair (73204 and 73209) will be fitted with MTU 12V 4000 R41 engines at Brush Loughborough. Both are currently at Brush and will emerge sometime next year as 73901 & 73902.

You burst into flames once or twice and some folk never let you forget it! :scared:

Interesting to see that Britain's only state owned multi-traffic operator is yet again getting its feet under a new table ;)  I wonder how many of them will be on hire to other operators?

One thing I wondering, is why the 88 isn't also third rail capable which would have covered pretty much every base?

 

Presumably it's not an operational need for DRS, but I can't imagine it would have driven the cost up too much (beyond the lack of testing facilities at Vossloh I suppose). Mind you that gap could potentially be covered by the 92 rebuild..?

My guess there is that it can happily run on diesel over third rail metals, and as lines such as Southampton - Basingstoke are going over to 25kV, the scope of use under the wires in the south east will be ever expanding.

Interesting little purchase by DRS. Essentially the 21st century's answer to a Class 90, however superior in every respect bar top speed, being 10mph slower. However, ETH, re-gen braking, modern AC traction motor's, and an extra 400hp on top of all that shall make it an extremely capable mixed-traffic beast, I imagine it should breeze up Shap/Beattock compared to a Skoda. It will be able to put more power down, it's more powerful, and with AC traction motor's and superior wheelslip control, it'll hug the rails more, important with a Daventry-Mossend on the draw-bar. The diesel engine looks like it can put out about 1000hp, so useful to limp to the next loop in the event of failure, and it might be able to do last mile hauls like Cumbernauld to Grangemouth depending on gradients etc etc. Looks like these will allow DRS to compete with DBS for the sleepers too. Thumbs-up from me on this order anyway! Makes me wonder how long double Can's and Skoda's have got with Freightliner though...

It'll need good sanding gear to avoid slipping on all the vomit spewed over the edge of the platform by people who look upon it and are immediately nauseated by the awful appearance.

Bit harsh, BD.  I rather like them and certainly a big improvement on the rather questionable Class 70.  I can't help thinking though that there has been some regression in loco design considering that fifty years ago we managed to produce considerable and timeless 'lookers' in the Hymeks, Westerns and Brush 4s.
