    Yes, I saw it at Euston last night. About 30 seconds including opening the gangway doors for passenger use.

    Cleaning the sick off a seat took a lot longer :(

    I’m not sure we needed to know that...

    In the UK, waggon development stagnated for a long time because of the widespread phenomenom of private goods waggons: The railways didn't own most of the freight waggons they were hauling.

    Still no further confirmation, information is a bit thin on the ground with this one.

    I'm beginning to think this was wishful thinking from some freight/toc company as it's all gone quiet on this front!

    More info on the Class 93 locos in the latest issue of RAIL which is already available digitally (physical edition on Wednesday 19/12/18). Ian Prosser tweeted an image of the cover on twitter which shows a concept image: https://twitter.com/IanProsser7/status/1073871292808523776
    The piece on these is based on an interview with Rail Operations Group's CEO - Karl Watts. First one is expected in August 2020. Initial order of 10 with an option for 10 more.

    So, a bit of progress, and an option for a further 10! Just a concept design at the moment, I reckon it will look pretty similar to the EuroDual they displayed at Innotrans. Now to find out in March what DRS have planned! I doubt very much this 93 will be seen up here in Edinburgh much, if at all!

    Another piece from RAIL here - https://www.railmagazine.com/news/n...s-fuels-its-ambitions-with-tri-mode-class-93s

    My guess based on that is that it's effectively an 88 with more power output on diesel. One of the benefits of having a battery pack is that you can deliver a big burst of power to the traction motors when the train starts from a stand, so it ought to deliver much better performance that its engine size might otherwise suggest. Lithium titanate oxide is used in some electric cars, and recharges very quickly compared with some other battery chemistries, so ideal for a hybrid setup where you want to discharge the battery as you start moving and then recharge it once you reach a cruising speed.

    Many thanks for the update. :smile: Not much of a guess, though, when it's specifically stated in the article (Unless more detail's been added in the past couple of minutes?):

    A big investment and change in direction by ROG's they must be confident of winning further work.

    Not only that but they’ve also reserved numbers up to 93050 according to the article (last paragraph)!

    Assuming you mean the last paragraph of the full article rather than the one posted online?

    Yes. The article in Rail not the post online.

    Bigger cooling system equates to a longer bodyshell, somehow I think the design may well differ slightly from that of an 88.

    Will it be Bo-Bo, or possibly Co-Co to keep the axle weight down? I know Stadler were very insistent that adhesion alone was never a reason to go with Co-Co, but there is a lot more equipment on this one.

    It's clearly shown as a Bo-Bo in the side profile mock-up in the RAIL article linked above.

    The initial concept drawing is a Bo-Bo but when you consider all the gubbins inside, the length etc may determine other.

    If you look at European locomotives, most are Bo’Bo’, even some of the most powerful ones.

    I believe continental railways have less strict axle loading restrictions, however.

    Although the Stadler electro-diesels that they are building (with CAT C175-16 engines, similar to Class 68) are Co-Co.

    Yes, I was going to mention such things as UK loading gauge etc could determine along with other factors the design of the 93, adding a battery and extra cooling equipment in a uk scale locomotive would require a different bodyshell design in this case. The "Platform concept" on which it is designed from, loans much from the 88, but it won't necessarily look like a 68/88. I would imagine it would look quite similar to the new EuroDual.

    Any particular reason why articulated bi mode locos haven't caught on especially in the UK with limited gauges and axle weights?

    Someone might know why! The closest we've come is probably the class 20s which tended to work in pairs coupled nose-to-nose.

    Spec for the 93 has a top speed of 110mph, just wondering if an opportunity has been missed? A 125mph-capable unit could be very handy.....

    Handy for what, though?

    And especially with the weight of transformers, diesel engine, and batteries would it not run into the same problem as the Class 67s of being uneconomical to run at that speed given axle loadings and resultant track access charges?

    MML or XC for a start.

    Why is there a number of people that think LHCS is going to make a comeback, when the evidence shows the complete opposite? And before some smart alec quotes TPE Mk5s at the, the only reason they were procured was reduced delivery timescales, and look where that has ended up!

    MML will eventually get a fleet of bimodes to replace the Meridians and derogated-HSTs while XC will be lucky to get anything at all in the short to medium term, apart from some more HSTs.
