I am doing some research for a new Downton Railway Station page and could use a little help on British railways. In episode 3.09 one car identifies the line as the NERC. I have found the NER (North Eastern Railway) which did serve York and surrounding areas in the time of DA up to 1923. I do not see any reference to NERC. Anyone know where the 'C' comes from? Was that the real logo or was there an issue such as copyright or trademark that the producers of DA were just trying to avoid?
