RMweb Gold beast66606 Posted December 9, 2019 RMweb Gold Share Posted December 9, 2019 Interesting article regarding new Flirts in Italy https://railcolornews.com/2019/10/30/it-stadler-flirt-bemus-for-valle-daosta-enters-service-but-not-without-problems/ Quote In an answer, dated from 21.10.2019, Stadler issued an apology for the recently caused inconveniences. The manufacturer confirmed that there are issues, related to the development of the rolling stock, and more specifically: ‘the interaction between vehicles and the specific railway infrastructure of the line.’ my bold. 5 Link to post Share on other sites More sharing options...

RMweb Gold beast66606 Posted December 9, 2019 RMweb Gold Share Posted December 9, 2019 Last week - which prompted the suspension of services - a unit had a wrong side failure on the Cromer line, the signals stayed at green behind it ! 1 3 Link to post Share on other sites More sharing options...

Cockup, yes but not actually the fault of Stadler. It's not as clear cut as simply blaming the new units. Of course the answer to that isn't yet in the public domain.

Cockup, yes but not actually the fault of Stadler. It's not as clear cut as simply blaming the new units. Of course the answer to that isn't yet in the public domain. That is definitely where I would start. There appears to be something about these trains which means they do not correctly operate some track circuits. That could mean there is smething in the specification/design which is not right and it also raises the question of whether or not the trains were specified as being required to reliably operate certain types of track circuit in all operating conditions? Far worse than all of that is this must raise some very serious questions about the test phase. Trains don't suddenly cease to operate track circuits they were correctly operating a few days or weeks previously - the laws of physics don't change by whim. What can change of course - as already mentioned - is wheel/railhead contamination (by leaves at this time of year). But leaves fall off trees every year so that should have been considered in the spec/design and one has to ask if that was not the case why was it not the case? Does the answer lie in very low unsprung weight and/or the wheel profile? 1 6 Link to post Share on other sites More sharing options...
Classsix T Posted December 9, 2019 Share Posted December 9, 2019 (edited) Well as a season ticket holder who had both his regular trains caped today, number one priority is to sort out the problem. AGA should then offer a discount on season renewals as a good will gesture. Then Stadler and Abellio can make some lawyers rich(er) by mud flinging and finger pointing in court. I do appreciate the discussion here though and await the RAIB report with interest. Typically, how long would such an undertaking take? C6T.

I'd be surprised if we see some sort of interim RAIB report in less than 4 weeks, I doubt we'll see the full report in under a year (and probably longer). In the meantime from everybody's point of view I trust that NR, the operator, and rolling stock owner are doing something to identify the problem then at least mitigate it sufficiently to get the trains back on their booked work before any longer term solution is implemented 3 Link to post Share on other sites More sharing options...

Stadler didn't build those trains. If they weren't told about the specific properties of them which makes them work then it's not their fault if they didn't include them. And if they were told and haven't built to the spec they were provided then it is their fault. My experience in engineering is that some suppliers do exactly what's specified whether it's right or not, others build what they want regardless of what the spec says, and some will work with the clients to get things as close to what they actually want (as opposed to what they asked for) as possible. I doubt we'll ever find out how this particular train supplying contact went, but my experience suggests that it all stems from how good or otherwise the initial specification is. It's not a new issue though. BR was quite capable of similar cock ups, remember the 158s having to run with vehicles from other units because on their own they didn't work with the infrastructure? 1 Link to post Share on other sites More sharing options...
Classsix T Posted December 9, 2019 Share Posted December 9, 2019 I recall an interview with the then Chief Exec of Railtrack/NR (probably the latter organisation actually) and for whatever reason I particularly remember that his major concern was that the new trains then being introduced seemed to bear little concern with axle loading weights. He stated something along the lines of ROSCOS via the TOCs wanting all the bells and whistles with scant regard to the resultant wear and tear on the infrastructure, both in terms of power consumption and track "damage". Arguably he may well have been showing his hand from higher ups demanding reduced costs, fair enough, but lighter and less power hungry was his mantra. Made sense to me at the time. My point being (eventually!) if indeed these units are light, which may or may not be contributory to their current woes, is that beneficial to the TOC in terms of track access charges hence its attractiveness?

RMweb Premium 31A Posted December 9, 2019 RMweb Premium Share Posted December 9, 2019 Stadler have built similar trains which have been working in all sorts of mainland European countries for several years and I haven't read of similar problems with them - it would be interesting to know what's different about these trains, or this country!

RMweb Gold beast66606 Posted December 10, 2019 RMweb Gold Share Posted December 10, 2019 A bit of an improvement today : Ipswich / Felixstowe - suspended East Suffolk - 2 hourly Ipswich / Peterborough - suspended Norwich / Sheringham - delays due to TSR Norwich / Cambridge - terminating at/starting from Ely, some cancellations proposed yesterday but quite a few (all ?) actually ran Ipswich / Cambridge - service restored Sudbury - service restored (actually retored yesterday morning) 2 Link to post Share on other sites More sharing options...
RMweb Gold russ p Posted December 10, 2019 RMweb Gold Share Posted December 10, 2019 I can't understand why they aren't trying to hire some stock, I know it wouldn't be too popular up north but hire 153s and 156s off northern and keep the 142s a bit longer. They couldn't be used on GA as no one signs them Then there is always the short set(s) but the modern railway is too obsessed with image to let BR stock replace their shiny new white elephants When BR had problems with 143s and 155s they used anything to keep the job running and 158s were kept out of it when it was realised they needed track circuit actuators until they were fitted 3 Link to post Share on other sites More sharing options...

Mark Saunders Posted December 10, 2019 Share Posted December 10, 2019 My thought is that it is a repeat of the problems with the 158s, as Russ' said Track Circuit Actuators were fitted and the three car sets additionally got scrubber blocks (tread brake blocks) on the outer bogies. It may be a combination of factors lightweight stock, disk brakes (unable to clean tyres), weather/railhead contamination. Mark Saunders 2 Link to post Share on other sites More sharing options...
