    Double third rail query

    Noted from a talk by Bombardier in 2016: Each train has two independently-powered ends and a trailer in the middle, so it will run with both pantographs up. There are 5 powered bogies (both axles in each) in a 4-car "half". One car with one powered bogie will be left out of each "half" in the...

    Double third rail query

    This question of bridging was raised earlier in the thread, but not answered. From TfL's datasheet for the class 378, the shoes are on bogies 1,4,7, and 10. Their spacing is 35,20, and 35m, so 90m between the outer shoes of one unit. That gap at New Cross Gate is at most 74m. So if it does...

    WCML Power Supply & Auto Transformer Upgrade

    This from something put out by SP Energy Networks: There will also be access rights (I think this is the same underground as overhead):

    Class 701 'Aventra' trains for South Western Railway

    Roughly speaking, it bears the same relationship to you local sewage treatment works as does your computer printer to a newspaper's web offset rotary printing press. Protec (a German maker of such things) claimed the first in service in the UK in 2019, in a Scotrail Class 334 (see thread). But...

    Calculating Railway Height

    They are neither! OS explains these record photographs thus: So these were basically intermediate points used in local surveying, especially in urban areas where you could often not see other surveyed points. Surveying required that you could see at least two points that were already fixed by...

    Calculating Railway Height

    I've actually never come across this, as it just wasn't a thing in the 60s when I was at school or university. Later I did have to address the same issues in designing sampling or digitisation strategies (strictly it's discretisation). The rule is different only in that it's a simpler version...

    What is the point of Old Oak Common?

    That document does not really cover discussions about the route and connectivity before the initial HS2 proposal in 2010. Serving Heathrow was part of the remit given to HS2, and in the route development it became closely linked with OOC, seen as alternatives. Serving Heathrow en route (like...

    Act of Parliament after a lines closure

    Looking at the details in the report and consultation document (links in the page referenced above), very few of the repealed acts saw a railway built. And even those ones were all closed a long time ago - typically over a century: So it may well be that the approach to more recent closures is...

    Act of Parliament after a lines closure

    The procedure for closing railways deals with running services, and does not go on to consider repeals. What has happened recently is that the Law Commissions draw up lists of obsolete acts, including railway acts, and then a bulk repeal act is passed. The last one (I think) was the Statute Law...

    Dining Car Attendant 1928 - 1939 St Pancras?

    Have you searched through the lists in Appendix 1 of the "Railway Workers" guide? For the grouping era, there are only four companies to consider! These lists are of record sets per company, of which there are three for LMS, only one is staff records, and that's about clerks and juniors. So it...

    Dining Car Attendant 1928 - 1939 St Pancras?

    According to the National Archives guide (link above), staff records of most of the main railway companies have been imaged and indexed by Ancestry. This includes the LNER and LMS. What neither TNA nor Ancestry tell you is how complete their holdings are - for the obvious reason that they have...

    Network Rail hopes staff will be 'amateur meteorologists'

    A poor choice of wording, obviously. Look at the next line of that report: "It wants to help staff to interpret weather forecasts to make better decisions during storms or heatwaves." So the idea is to equip their staff, who have to make use of weather forecasts and meteorological data in the...

    RENFE train at Plouaret, Brittany.

    Déshuntage is the standard term for a train failing to activate a track circuit. Usually it happens with the lighter single-car trains, some of which have been banned from running singly as a result. So shuntage,while less common, refers to a train being a shunt, or low-resistance parallel path...

    Derailment near Grange Over Sands

    Tim Farron (local MP) has got hold of some interesting information. From cumbriacrack: Some of that is typical MP making a noise stuff - though I doubt NR have the nerve to reply "we are still awaiting official notification of your appointment as replacement for the RAIB; until then we will...

    Derailment near Grange Over Sands

    I assume we are looking into a void where the side has been dug away, creating a sort of cave mouth. It looks just as in the contemporary description of the construction (post #68) - a pile of estuary sand/silt, capped by a layer of clay, with quarry waste ("rids") and then ballast on top...

    Derailment near Grange Over Sands

    We had a quote in post #81 from The (NWE) Mail, about the golf club (and perhaps their neighbours) doing work on the Seldom Seen culvert: He (a director of the club) also said: That may be optimistic - the expert view is that this part of Morecambe Bay is filling up with sand, so while the...

    Derailment near Grange Over Sands

    I expected there to be an internal drainage board for an area like this, but could find no trace of one. There was a consultation run by the Environment Agency in 2015 on their proposal for an IDN for South Cumbria, which would include the Winster catchment and much more. In it I found this...

    Derailment near Grange Over Sands

    There is no culvert under the collapse site. The western exit from Meathop Drain, the Seldom Seen culvert, emerges under C J Atkison's builders yard, close to Blawith Point. Its exit channel across the sands is visible in the 2021 Google Earth image; usually it isn't Network Rail's small pump...

    Century old LNER wagon unearthed in field near Antwerp

    Yes, that does answer the question about where LNER ferries docked. The D'Herbouvillekaai is roughly over the Kennedytunnel, near the southern limit of the old city. But far (ca. 4 km) from where this container is now - it must at some stage have been worth moving, and then not worth recovering...

    Century old LNER wagon unearthed in field near Antwerp

    NLS have WW2 British military maps of Belgium, but they are small scale ones and based on WW! originals with an unknown amount of revision. So this one, while dated 1943-44, should be seen as pre-war but of no specific date. (Ignore the pointer - it's not where I put it on the map!) I have...
