You probably cannot read it at the image, but the TVM and KVB switches a have the label Isolé, which is in French language. I am wondering if this is a bug or authentic.
Considering the whole KVB "box" in in French I would guess it's accurate, as they use the same parts used on the TGV
TVM and KVB are French systems so I'm sure that's how it is in real life. CTRL is set to French standards for international Eurostar traffic and Southeastern 395s are simply set up to run on part of it for a speedy commute.
As much as it is a French system... I wouldn't be so sure as if to say it must be in French. Would probably need a word on this from someone who is driving Javelins. I'd say 50/50 possibility it's right
Where is KVB actually used in the real world (in the UK - I realise it's widespread in la douce France )?
only on the slow section of high speed rail in the UK, so probably only there and maybe in a eurostar yard in the UK?
