    I've not seen anything written other than by a general purpose
    journalist so I'd treat anything I've read with suspicion. Something
    might have been lost or gained in the translation as well.

    I've seen it in multiple reports. They're probably written by ordinary journalists, but it looks like they're quoting a
    more expert source. After all, ordinary journos wouldn't have a clue what a fishplate was ? an item of crockery,

    Perhaps someone (or a translation system) thought fishplate is a generic
    term for joining rails. It's a weird enough word that people might not question it as jargon.

    Spanish train driver did not know of fatal crash for four minutes
    From
    https://www.telegraph.co.uk/world-news/2026/01/21/spanish-train-driver-not-know-fatal-crash-four-minutes/

    A Spanish train driver whose carriages derailed and smashed into an
    oncoming high-speed train, killing at least 43 people, did not initially realise there had been a crash, telephone calls reveal.

    The rear carriages on his Iryo service from Malaga to Madrid came off the tracks near Adamuz in Andalucia on Sunday evening, colliding seconds later
    with an Alvia-operated train from Madrid to Huelva.

    Audio recordings analysed by investigators showed chaos in the aftermath of
    the crash, with neither the driver of the Malaga-Madrid train nor the
    control centre realising there had been a crash or even a derailment.

    The driver at first reported just ?a snag near Adamuz? to Madrid?s Atocha control centre, and it was only after climbing down from the train ?to
    inspect it and seeing the damage to the rear carriages that he called for ambulances.

    Moments after he made his first phone call to control at 7.45pm on Sunday, emergency brakes could be heard screeching in the background, according to
    a transcript of the audio recording obtained by El Pais.

    Neither the driver nor control centre operator appeared panicked as they discussed how they should assess the source of the ?snag?.

    A minute later, another train in the area but not involved in the collision reported a lack of voltage on the railway to the control centre.

    Seeing the Alvia train had also stopped, the operator then tried to ring
    its driver but the call was unanswered. The driver was already dead.

    He then spoke to the train?s conductor, saying: ?I?m calling you from the control room at Atocha. I?m trying to call the train driver and I can?t get through to him, see if you can put him through.

    The conductor replied: ?I have a bump on my head. I have blood on my head.?

    The operator responded: ?What? Excuse me??

    It was only in the following conversation with the Iryo driver that they started to understand the scale of the disaster, four minutes after their
    first call.

    Clearly in distress, the driver said: ?There?s a derailment and I?m
    encroaching on the adjacent track ? I need you to stop the traffic on the tracks urgently, please.

    ?I have a fire too. I need you to send, please, emergency services, firefighters and ambulances, because I also have injured people on the
    train.?

    ?scar Puente, Spain?s transport minister, said on Wednesday that the time between the derailment and the collision was just nine seconds, giving no
    time to brake.

    Investigators are still looking into the cause of the initial derailment,
    which they believe may have been caused by a crack in the railway line.

    Two days later, another train derailed after a wall collapsed onto the
    track near Barcelona, killing the driver and seriously injuring four passengers.

    Semaf, Spain?s largest train drivers? union, has called for a nationwide three-day strike to demand assurances over safety after the derailments.

    ?We are going to demand criminal liability from those responsible for
    ensuring safety in the railway infrastructure,? the union said.

    The crashes have caused widespread disruption for commuters and travellers.

    Yes and no, as LZB and line block should not have admitted
    anyway more trains to that section.

    But indeed is was wise not to send more trains.

    Oh, and one wheel of the Iryo train is missing, and not yet located. So
    there remains the possibility of a wheel disintegration.

    Some of the reports talk of a worn fishplate in the track. Do you get these
    in cwr track? Or, only at points?

    And if the track was replaced as recently as last May, would you expect
    wear severe enough to cause a derailment so soon?

    My GF comments "it's not unusual for recent maintenance to involve
    not-doing-up-the-bolts-afterwards sufficiently". Indeed, it's common
    cause of mechanical failure.

    That?s certainly true, and if the accident had happened within a few weeks
    of the new track being laid would point the finger at a track fault. But
    eight months later? Wouldn?t you expect a fault to have been spotted by
    then?

    And, of course, the fault would be probably more likely in the points than
    the rails.

    How long did it take for the setup at Potters Bar or Grayrigg to come apart
    after maintenance? The answer is that we don?t know. Both sites had had
    recent inspections (allegedly[1]) but they may have been purely visual, and
    it?s not clear when the last manual inspection was made of how tight the
    nuts and bolts were.

    [1] In the case of PB it seems that there was some doubt about whether the
    previous day?s inspection was actually made, and at Grayrigg NR admitted
    the previously scheduled inspection had not taken place.


    I would think, based on their location, these crossovers are used
    relatively infrequently, so the points probably don?t get used much. But
    perhaps another train had used them earlier that day, and they hadn?t
    locked properly when returned to their normal position?

    The reports of a loose fishplate joint confuse me. This is modern cwr, so
    where would there be fishplate joints? Perhaps they are actually expansion
    joints where the cwr connects to the switch? So, if such a joint failed,
    just before a switch, it would explain why the derailed back end of the
    train got pulled to the left, on to the other track. That, in turn, pulled
    a couple of other carriages on to the other track.

    Trade union(s) calling for industrial action in order to get drivers'
    protection from such accident. They said complaints had been addressed
    for the given portion of track weeks ago...


    That's odd, because that track is new.

    Quality welding/repair yes/no? No pieces missing,
    all screws or similar applied with the correct
    torque?


    It was installed eight months ago. Any such faults would have been found very quickly.

    Yes, as already mentioned, there was indeed a broken rail (in fact, lots of rail damage), and points and one wheel that was missing from the vicinity
    of the accident (but eventually found 900? away. Any one of the these could have been the cause of the derailment, with the others happening as a consequence.

    The derailment would have happened well before the point where the Iryo
    train ended up, as even a partially derailed train travels quite a long way
    if travelling at over 125 mph.

    Spain suffers third serious train crash in five days as commuter service
    slams into crane

    A third serious train crash has taken place in Spain in five days - after a commuter train hit a construction crane in the southeast of the country.

    The ?crash ? in ?Cartagena in the Murcia region left several people
    injured, including one seriously, state broadcaster TVE reported on
    Thursday.

    It came after ?Sunday's ?deadly high-speed train ?collision in the southern Andalusia region that killed ?at least 43 ?people and another train
    accident in northeastern Catalonia on Tuesday in which the train driver
    died.

    Spanish rail operator Adif said on X that traffic on that line was
    interrupted ?due to "the intrusion ?into the infrastructure gauge by a
    crane not belonging ?to the railway operation", without providing further ?detail.

    Yes, that suggests something less than a full bogie. Presumably something
    that large would have been found much more quickly?

    Elsewhere, I?d read that a wheel was missing, but that could, I suppose,
    have been an axle set.

    Again, of course, this could be the cause or a result of the derailment.

    For example, suppose there was indeed a broken rail weld or expansion joint that cause a bogie in the last carriage to derail. The broken rail was on
    the outside, so the wheels would have been displaced outwards. But if they
    then encountered the points for the crossover, that would violently jerk
    the derailed bogie to the left, possibly breaking the wheel or bogie, and causing the carriage to slew to the left, into the path of the oncoming
    train. The derailed last carriage also pulled the seventh and sixth
    carriages across.

    The southbound train hit the derailed train at an acute angle, which pushed
    it off the side of the embankment. So it was damaged by the collision with
    the first derailed train, but then really smashed up as it dived on to the ground at speed.

    Some of the reports talk of a worn fishplate in the track. Do you get these
    in cwr track? Or, only at points?

    And if the track was replaced as recently as last May, would you expect
    wear severe enough to cause a derailment so soon?

    My GF comments "it's not unusual for recent maintenance to involve
    not-doing-up-the-bolts-afterwards sufficiently". Indeed, it's common

    That?s certainly true, and if the accident had happened within a few weeks
    of the new track being laid would point the finger at a track fault. But
    eight months later? Wouldn?t you expect a fault to have been spotted by
    then?

    And, of course, the fault would be probably more likely in the points than
    the rails.

    How long did it take for the setup at Potters Bar or Grayrigg to come apart
    after maintenance? The answer is that we don?t know. Both sites had had
    recent inspections (allegedly[1]) but they may have been purely visual, and
    it?s not clear when the last manual inspection was made of how tight the
    nuts and bolts were.

    [1] In the case of PB it seems that there was some doubt about whether the
    previous day?s inspection was actually made, and at Grayrigg NR admitted
    the previously scheduled inspection had not taken place.

    The reports of a loose fishplate joint confuse me. This is modern cwr, so
    where would there be fishplate joints? Perhaps they are actually expansion
    joints where the cwr connects to the switch? So, if such a joint failed,
    just before a switch, it would explain why the derailed back end of the

    a couple of other carriages on to the other track.

    Not all bad welds break up under the first train.

    Agreed, but there would have been thousands of trains, and hundreds of thousands of wheels that have passed over this
    track section since it was installed. One would expect a serious fault in the welding or heat treatment to have come to
    light before now. So, we still don't know if this was cause or effect ? it could be either.

    Looks like similiar damages to the wheels have been seen on
    other trainsets too, and more trainsets will be looked at for
    this purpose.

    Yes, it should trigger a system-wide check of the wheels and tracks. We had a similar problem with gauge corner
    cracking here in the Hatfield derailment and crash, which caused immense disruption for ages.

    Maybe after it derailed the bogie was sticking out sideways then got whacked

    Similar to.. .? Neither train has power cars, they both use distributed
    power. The class 120 uses all 1A bogies with one axle powered by cardan
    shaft from a body mounted motor. The FR1000 uses Bo bogies, i.e. with both axles powered, and some unpowered bogies. The NYT image shows what looks

    Looks quite similar to me if you look at the remaining bogie of the power car.

    Similar to.. .? Neither train has power cars, they both use distributed
    power. The class 120 uses all 1A bogies with one axle powered by cardan
    shaft from a body mounted motor. The FR1000 uses Bo bogies, i.e. with both >> axles powered, and some unpowered bogies. The NYT image shows what looks
    like one traction motor attached to the bogies and the mounting for
    another, now missing. The class 120s also have gauge changing wheelsets
    and I don?t see any evidence of that in the photo.

    I wonder what could cause a whole bogie to get detached, and then fly so far?

    Maybe after it derailed the bogie was sticking out sideways then got whacked
    by 200 tons moving at 180mph.

    Difficult to say without seeing the intermediate terrain, but that?s
    doesn?t seem impossible.


    Wouldn?t the bogie look more damaged in that case?

    It?s missing a traction motor at one end and the wheelset at the other,
    along with various fittings visibly broken or absent on the side facing the camera. Not sure if the bogie frame might have been bent or broken in such
    a collision. It?s also upside down.

    Do we know which coach the bogie is missing from?

    I think it?s the inside (front) bogie from the last coach, so probably the
    one that first derailed. It?s missing in images of the underside of that carriage.

    https://www.nytimes.com/2026/01/20/world/europe/spain-missing-part-undercarriage-key-investigation.html

    The bogie is simply missing, without major damage to the body around it.

    I think that?s consistent with it first becoming derailed due to a broken
    track joint, moving slightly to the right, then clouting the diverging
    points at almost 125 mph. That impact might be enough to shear the bogie
    right off, throwing it to the left at high speed, with that carriage also
    being jerked forcefully to the left, hard enough to also derail the two carriages ahead of it. A few seconds later the approaching Renfe train
    smashes into these carriages, which get pushed over to the right, while the Renfe train gets pushed off the embankment.

    This happened on an embankment, so the flying bogie would have been
    launched up into the air, and had a ballistic trajectory, hence the long distance it travelled.

    i?m not sure that?s quite true - there?s a lot of grazing damage to the underskirt along the side of that last carriage, especially at the leading
    end under the doorway, and possibly to the doorframe. What we can see of
    the coach in front doesn?t show quite the same pattern and its doorframe is largely intact.

    I think that?s consistent with it first becoming derailed due to a broken track joint, moving slightly to the right, then clouting the diverging
    points at almost 125 mph. That impact might be enough to shear the bogie right off, throwing it to the left at high speed, with that carriage also being jerked forcefully to the left, hard enough to also derail the two carriages ahead of it.

    Plausible.

    The trailing driving car is missing the inner bogie, failrly obviously

    We know that one isn?t attached; we don?t know if that?s the one they

    the first bogie to have derailed, and also at the point of impact of the
    two trains.

    To fly that far, it must have taken a huge lateral force, either during the derailment itself, or when the other train collided with it. I don?t think
    we here know enough about the relative positions of the bogie, the point of derailment and the point of collision to say which.

    MADRID, Jan 23 (Reuters) - A fracture in the rail appeared to have occurred before a high-speed train derailed in southern Spain last Sunday, rail
    accident investigating body CIAF said in a preliminary report published on Friday.

    Sunday's deadly collision in Adamuz, Cordoba province, killed 45 in one of Europe's worst train accidents. A first train belonging to private
    consortium Iryo derailed and smashed into another oncoming high-speed train from state-owned rail company Renfe.

    "Based on the information available at this time, it can be hypothesised
    that the rail fracture occurred prior to the passage of the Iryo train
    involved in the accident and, therefore, prior to the derailment,"

    CIAF said the causes for the breakage had yet to be established and nothing
    had been ruled out.

    Reuters wrote on Tuesday that investigators had identified a broken joint
    on the rail track in an exclusive report.

    The Transport Ministry did not immediately reply to a request for comment. Iryo's majority owner, Italian state-controlled railway group Ferrovie
    dello Stato, declined to comment on the report.

    Investigators found uniform notches on several of the wheel treads on the right-hand side of the Iryo train, according to the report.
    The marks were consistent with the wheels striking the top of a rail, and a visual comparison suggested the wheel notches match damage seen on the
    broken rail section at the derailment site, it added.

    CIAF said it had also found similar wheel damage on other trains that
    passed through the area before the crash.
    The report's findings must be confirmed by further calculations and
    detailed analysis, CIAF cautioned.

    With USA stock it doesn't even need to be major since they don't attach their bogies to the vehicles at all, the latter just sit on top of them. A good demonstration here:

    Oh, that one. I kept wondering if they inspected the overbridge
    afterwards, or whether it?s just built to have wagons grind themselves to
    death on it.

    (And of course there are brake lines between the bogies and the frame, but they?re not going to do anything to hold the wagon together.)

    With cwr under tension, I assume that when a rail completely fractures, a gap opens up? How big might it be?

    I wonder if the previous wheels that got notched as they passed over the rail break made loud banging noises as it
    happened? Would passengers have felt bumps?

    Good question. Next question - how big did it need to be?

    <https://youtu.be/agznZBiK_Bs>

    The photo of three people inspecting the broken rail shows a section of
    rail overturned after the broken section. It?s not that long - you can see
    the rail in its normal state at the left edge of the picture - but it?s
    longer than the US Army recommended, and higher speeds and smaller wheels
    might change things anyway.

    I wonder if the previous wheels that got notched as they passed over the
    rail break made loud banging noises as it
    happened? Would passengers have felt bumps?

    There are reports which may be exactly that - passengers reporting rough
    riding on that section of track prior to the accident.

    I found a good image of a RENFE Class 120 bogie earlier, but now I can?t
    find it again. It?s quite different.

    Looks quite similar to me if you look at the remaining bogie of the power car.

    Similar to.. .? Neither train has power cars, they both use distributed >>>>> power. The class 120 uses all 1A bogies with one axle powered by cardan
    shaft from a body mounted motor. The FR1000 uses Bo bogies, i.e. with both
    axles powered, and some unpowered bogies. The NYT image shows what looks
    like one traction motor attached to the bogies and the mounting for >>>>> another, now missing. The class 120s also have gauge changing wheelsets
    and I don?t see any evidence of that in the photo.

    I wonder what could cause a whole bogie to get detached, and then fly so far?

    Maybe after it derailed the bogie was sticking out sideways then got whacked
    by 200 tons moving at 180mph.

    Difficult to say without seeing the intermediate terrain, but that?s >>>>> doesn?t seem impossible.


    Wouldn?t the bogie look more damaged in that case?

    It?s missing a traction motor at one end and the wheelset at the other, >>> along with various fittings visibly broken or absent on the side facing the
    camera. Not sure if the bogie frame might have been bent or broken in such
    a collision. It?s also upside down.

    Do we know which coach the bogie is missing from?


    The trailing driving car is missing the inner bogie, failrly obviously
    that one.

    We know that one isn?t attached; we don?t know if that?s the one they couldn?t find. It seems to be fairly common for bogies to come away from vehicles when there?s a major crash.

    It?s almost certainly the one that derailed first ? we know it started with the last car.

    It is indeed not that rare to have a train
    derailing from broken rail not from the very
    first part of the train: https://www.railwaysarchive.co.uk/documents/DoT_Bushey1980.pdf
