Some recent period MPCs

[Pumbaa]

These were posted elsewhere so I'm grateful to those making it available.

These are the three highest MPCs from the last period according to the official figures released by ATOC.

3) class 159/0 with 145,909
2) class 458 with 229,005
1) Class 350/2 achieved 382,240.

I don't know which is more remarkable to be honest. A BREL DMU achieving that figure, or a previously run down poorly designed and manufactured Alstom product, or the undeniably successful Siemens product!

I think the 458 is the most remarkable. You kind of expect that from the 350, but the 458 has a very chequered reputation.

 

[Lampshade]

Is this fleet wide or average per unit? 458s were averaging 4,300 MPC in 2004, a testament to what the magicians at Wimbledon have managed to achieve

 

[Pumbaa]

Fleet wide.

Still over 300k is damn respectable.

 

[jopsuk]

Those figures translated to average-per-unit (for comparison to that historical figure- MPC is comparable whether fleet wide or per unit)
Class 159/0 6632.2
Class 458 7633.5
Class 350/2 10330.8

Are those really MPCs and not monthly fleet mileages?! I'm not convinced because I've not seen figures like that for anything in the UK (though I've no MkI stats to hand).

 

[Smudger105e]

I agree, those figures seem rather high to me. We are pleased with anything approaching 50,000 mpc with the 66 fleet...

I am pretty sure I read recently that the XC 220s were now the most reliable diesel units at something like 35000MPC so that figure for the 159s seems a bit ropey. And I know Electric units are more reliable but 382000 between failures is unbelievable in my opinion

 

[Pumbaa]

They are definitely MPCs, touted as some of the highest ever.

Clearly all fleets have highs and lows of MPCs which are smoothed out to deliver an MAA which gives a more indicative picture of the year as a whole, but these MPC highs are considerable highs nonetheless.

 

[Chris125]

Dont forget that these are peaks, albeit impressive ones - the moving annual average (MAA) smoothes them out and gives a more balanced view. Shows what is possible though!

Given this is ATOC we're talking about here, the figures will be MPC but distorted in some way, such as taking figures for one week and replicating the trend over an extended period, taking the top ten units in the fleet to use as the sample, or even just adding the fleet wide cumulative mileage before a single failure together.

Either way, it's not *actual* MPC data that we'd take as Gospel, yes it's a good indicator but take it with a pinch of salt.

One hell of a period then!! A stupiod improvement on p08 MTIN figures of 350/2s at 41k period / 35k MAA, 458s at 76k period / 41k MAA, we don't get to see DMUs so can't call 159s.

Excuse me Gents, as a casual railway enthusiast can you please tell me what 'MPC' stands for? I assume from the posts it's miles per ??. I've trawled the internet but found nothing. Thanks

 

[ainsworth74]

Miles Per Casualty and I think casuality is defined as anything that adds a five minute delay or more to the journey and is attributable to the train rather than say the signalling.

Miles Per Casualty - as it sounds, the average number of miles a unit covers before a failure

EDIT: Already explained.

 

[dangie]

Many thanks.

Apply a bit of common sense here....

There's 37 350/2's. If they only had casualty in the period that figure would mean that each and every unit was averaging just over 1,300 miles each and every day of the period, or 490k miles per year. Which they don't, and obviously the more casualties they had in the mythical period the greater the daily and annual mileage would have to be in order for the figures to be the MPC's as you claim.

These aren't MPC's, I'll have a look at the last few period's NFRIP figures at work tomorrow and see what the figures for the fleets in question actually were.

Now confirmed - UK record for the most reliable passenger train.

[Chris125]

London Midland Class 350/2 fleet sets new industry standard

"The Siemens Class 350/2 fleet operating London Midland services on the West Coast between Birmingham, Northampton and Euston recorded no technical failures in the last four week period"

"This is equivalent to 382,240 miles between technical failures"

Wow. Are we ever likely to see an Electrostar approach that?

Chris

 

[Pumbaa]

A small point of order - MPC is now any cumulative delay of 3 mins or longer, not 5.

Siemens lead in this year's Golden Spanners, and the 458 beat Hitachi 395s roundly, so expect some more squealing from them like last year.

 

[asylumxl]

Good advertisement as to why Bombardier shouldn't get the TL or CR orders...

OK, now I'm convinced - that is frakking incredible. When I saw the figures earlier I considered making comparisons to EMUs operating in Hong Kong, where their 'casualties' are triggered after 3 minutes, or at least they were when I read the NFRIP figures a few years ago. So it's funny you should say this...

The most recent Miles per Technical Casualty figures from TPE are:

Class 185 - 29,167
Class 170 - 27,854

A technical casualty is where a train has been delayed for 5 minutes or more during the course of its journey due to a technical fault, irrespective of whether that time is recovered during the course of the journey).

Since period 1 this year, all TOCs as mandated by ATOC now measure per 3 mins. TPE may report its figures internally in a different manner, or not updated the pro-forma text that is released with them. Nice to see the 170s not far behind the 185s, which I'm a little disappointed in - I thought they'd have been higher.

This is reported internally as "Miles per Technical Incident" - "A technical incident is where a train has been delayed for 3 minutes or more during the course of its journey due to a technical fault (irrespective of that time being recovered during the course of the journey)".

For info, the figures are Class 170 22,283. Class 185 17,500.

 

[Pumbaa]

Ah I see. Thanks for the clarification.
