[UK-CONTEST] OT- Railway electrification

[Clive Whelan]

Thanks John

That's quite encouraging. I do get some transient static here from the 
diesels in fact. Of course the line is fairly busy, but not like e.g. a 
main road with continuous traffic..Cynics have said that it could take 
double the projected time of 8 years to complete!
