- dspillett 15y agoCross Country trains (what was Virgin's bit of the rail franchises) are worse for this than anything else on the UK rail network. I'm told it is due to a combination of the materials in the construction of the carriage frame, and the anti-glare layer in the windows. If you are at the end of a carriage, signal strength/reliability seems to jump a bit when you are sat at a station and the doors are open. Other trains don't seem nearly as bad. I'm not sure how much of that is due to different construction or (in the case of other modern(ish) rolling stock) anything like the repeaters you mention (though as all the franchise owners are cheap-arses I very much doubt that tech has been paid for by any of them!).
