Default Mark III refurbishment

http://www.railwaygazette.com/nc/new...o-service.html

Railway gazette 31 May 2012

Quote:
UK: On May 28 Chiltern Railways put into service the first of four rakes of Mk III coaches that are being heavily refurbished and equipped with sliding plug doors.

Deployed on London Marylebone - Birmingham Moor Street services, the Mk IIIs are marshalled between a Class 67 locomotive and a Driving Van Trailer equipped with an auxiliary generator.

Next to each DVT is a GFW car inherited from the Wrexham & Shropshire fleet which has 30 seats in 1+2 formation. This is the 'Business Zone' with a small buffet counter, and a supplement is collected on board for use of these seats. The other four cars have 2+2 seating but with 72 seats in the two TSO cars and only 69 seats in the two TSOL cars equipped with an accessible lavatory.

DB Regio awarded a contract to Wabtec Rail Ltd of Doncaster to comprehensively refurbish a total of 20 Mk III cars. The aim is to have all four rakes in service by December.

Perhaps the most difficult task was to install the powered doors, with both ends of each car body removed and rebuilt to produce a larger vestibule with tracks for the sliding plug doors. Rail Door Solutions supplied the door systems, similar to those installed in the Siemens Class 444 Desiro EMUs for South West Trains.

Retention toilets compliant with the Persons with Reduced Mobility TSI have been installed. LED interior lighting has been installed throughout the TSOL cars and in all the vestibules, and there is a power socket available at each seat.

'This really does prove that you can deliver a first class service utilising older rolling stock', said Chiltern Engineering Director Kate Marjoribanks. 'The new power doors and additional features allow us to increase capacity and at the same time meet the needs of our passengers'.

Railway Gazette International was told that the next steps were likely to be adding a sixth car to each rake, and then producing a fifth rake to provide heavy maintenance cover.

The mainline sets are very impressive, cost per coach is upwards of 400,000 EUR. The dynamics of the UK market make such expenditure worthwhile. They basically have turned a Mk3 into an Irish Rail Mk4.

They wouldn't be that regessive surely ? !

Inside the coaches are very similar to the Irish Rail Mk4, the disability access regulations mean the layout more or less has to be the same.

At 250-300,000 EUR per coach IE's overhaul was deemed uneconomic so ICR's were got instead as the cost per km was almost 50% less.

What cost are you referring to ? Fuel cost ?, maintainance cost ? staffing cost ? Track costs ? Over what equipment life-cycle ?

Not sure, for instance, that the cost of operating a six-car railcar from Dublin to Galway would be cheaper than a six-car Mk3 push/pull.

Mind you it is fairly academic now as we have a railcar railway with virtually no freight. Not that long ago it was possible to occupy locomotives on an almost 24 hour basis (with obvious operational efficiencies) but there is very little opportunity to gainfully employ railcars between about 2200 and 0600.

The current ICR fleet is to a considerable extent a product of the Celtic Tiger era and a fair portion of it was purchased using funds that the NRA couldn't burn up quickly enough. Had the normal rules of economics applied I somehow suspect that Mk3s would still be in traffic, refurbished, and with a good ten to fifteen years of life remaining.

I hope the ICRs last the pace and deliver the economies you suggest because it is likely to be a long time before capital is available for replacements.

Its cheaper to operate an ICR, 3, 6 or 9 coaches all good for 100mph, no need for a guard and the fuel consumption per mile is less.

ICR reliability is running at about twice Mk3+201.

While the refurbishment looks cheaper, the projected cost to overhaul the Mk3 push pull fleet came to over 25million!

I think it said that operating an ICR fuel wise is €6 per km in the 2030 rail vision. If thats correct what would the 201 class be around?

Think the ICR may be kinder to the tracks more than the 201.

Due safety limitations Mk3 needed 8 coaches to operate at 100mph to make the braking distances.

So while a Mk3+201 is actually fuel efficient when in 8-9 coach length few if any trains in Ireland require such capacity

If it was me doing it, I'd look at dispensing with the existing PP and EGV units, instead buying more Mark 4 DVTs and converting the Citygold cars in each refurb set (toilets, PIS, wifi, power sockets, pushpull) to act as a "transition" vehicle which would present the same interfaces for coupling, power and control as Mark 4 stock do to their DVTs.

But it's not me, and it's not happening, not least since it would also require reactivating the stored 201s, possibly requiring PP on some or all of them, and reduce the projected life on the 100mph sections.

The cost crossover between multiple units and locomotive hauled trains is generally accepted as around 5 or 6 vehicles. A rolling stock options report for Metrolinx in Ontario, Canada states "The break‐even point varies by service profile (distances between stops, maximum speed, profile) and by unit costs (mostly locomotive – rebuilt, new diesel, or new dual‐mode). This point is typically four to five units for single‐level DMUs and five to six units for double‐deck DMUs."

As regards Mk3 formations there were indeed restrictions on train speed for short formations - can't remember the number but it certainly wasn't as high as you suggest - closer to five vehicles if I recall correctly.

As someone who reads a lot of their stuff, take anything Metrolinx say with a large pinch of salt or at least look for corroborating studies. These are the guys who stood over a study of 10-12 car EMU trains to replace loco+9/11 duplex trailers+duplex DVT by using conjugated 3-4 car EuroEMUs (Coradia) as a comparator rather than the more similar train consists operated in places like Chicago. (see p29 of this PDF)

This Chiltern HSTs were being held back by the dwell times caused by slam-doors. This will be an improvement.

Sadly I can only see the carriages ending up been scrapped. Unless Iarnród Éireann uses them on the Dublin to Belfast service (and quickly before they rot away any more) they have no future on their network. If money and capacity wasn't an issue I would love to see the push/pull service on the Limerick to Limerick junction shuttle service and GAA/football/rugby specials (least it wouldn’t really matter if the drunken fans urinate in their pants whilst seated, yes I seen it happen few times on the mk4’s). 2700/2800s could then be scrapped/sold

given the state of the economy and the ongoing cuts in IE the mark3 are history, IE have a surplus of ICR's as it is and from what we are hearing in the media about the cuts in workers we are going to see them worked a lot more.
