    Class 810 for East Midlands Railway Construction/Introduction Updates

    I was referring to the 8xx fleet in general and not specifically the 810s.

    Class 810 for East Midlands Railway Construction/Introduction Updates

    You've taken the words right out of my mouth! The 8xx fleet of trains appear to be nothing more the high speed commuter stock. They certainly do not have the feel or the ambience of what I would class as an InterCity train in my experience.

    TfW class 398 Stadler Citylink tram trains

    The Eurostar pantographs are lowered and then raised at Westenhanger when changing between HS1 and ET catenary configurations. The ET catenary is considerably higher than that on HS1 for obvious reasons.

    IET availability

    There’s quite a comprehensive article about this issue in the January 2026 edition of Modern Railways. Will probably make uncomfortable reading for some me thinks...

    Do trains using electric traction ever get mistakenly routed to or stop at short track which has no supply?

    It's a separate pan for operation on 25kV AC on the 373s. The DC pan is much heavier for coping with the heavier current demand. The DC pan can, however, also be used on AC subject to a restriction in maximum speed when on the HSLs. Not sure if this is the case with the 374s due to the...

    Major Signalling Loss at Sheffield (10/02/2024)

    Many cables still have to be electrically conductive for supplying power etc. Fibre cables cannot do this.

    How are speed limits set?

    That's one of factors. 1707377933 Both of these factors are taken into account. The distance between the first caution (yellow) aspect and the associated stop signal should not be less than service (normal) braking distance.

    How are speed limits set?

    OK, let's be pedantic. To run a single captive train at any speed does not require a signalling system but that wasn't my point. I'm a signalling engineer by the way...

    How are speed limits set?

    That's not how signalling works...

    How are speed limits set?

    Braking distances. The right to speed is dictated by the ability to stop!

    Failure to lower pantograph

    Eurostars change from 25kV HSL to 25kV ET (and vice versa) on the move nesr Westenhanger. This involves lowering and raising the pan. Similar process in France and in Belgium.

    Station announcer phraseology no longer used

    Heard today at Stratford: "The train is delayed due a fault on the train in front of this one" Sounds very clumsy, surely "....preceding train" would be better!
