These show the broad gauge lines of the Cornwall railway and the standard gauge of the GWR respectively. The signal box is shown too. I will keep you up to date if I find more details. There are some aerial photographs of the Iron Age fort too at English Heritage (Resugga). They aren't accessible here at present, but there is some detail that an expert might have better knowledge as to what is what. I have also found newspaper cuttings about the tramway and a further proposed line in the area, I will send them if you think they could be of interest to anyone. Thank you for all the updates, once again, I really enjoy the website and spend hours reading and reviewing the items. It gives me a great deal of pleasure! Kind regards, Michael Dowrick Yes it is all of interest, many thanks,
