Shielding 750 volt 3rd rail ?

It has always seemed to me that the 750 volt 3rd rail is a bad idea. snip So I have been thinking of the possibilities of shielding the 3rd rail. snip Other people have designed such systems too. There is one already in operation in London - the DLR. To complete this would obviously be a 10 or 20 year project, (even longer to replace some of the longer-lived stock with higher voltage stock) but some of the benefits, such as no icing in winter, would come immediately. Your design includes a plastic cover over the top of the rail. Doesn't this prevent existing stock from using rails fitted with your plastic covers? I don't understand how you intend to operate during the 10-20 year conversion period. Also, have you done any sort of cost-benefit analysis for this project? -- Richard J.
