Thanks - I might have to have a watch of that then. The name rings a bell.The LNER one looks to be of the Thompson-design that you can see in the film Elizabethan Express in the formation of said train.
I hadn't thought about trying to make them functional but that would be an interesting project I expect. Would some kind of tiny fibre-optic cable (I think that's the right stuff - you get it on some Christmas trees) work I wonder?I don't think anything other than Pullmans had the table lamps. Overhead lights could work or if small enough LEDs could be used to replicate reading lights in compartments?
