Someone kindly pointed out a link to my astonishment, for the 'Helford Valley Railway' (http://www.hvr.org.uk/). I thought to myself, wow, this is probably the best thing that's happened for my inspiration, the fact that THERE LITTERALLY WAS A NARROW GAUGE RAILWAY RUNNING NEXT TO MY HOUSE!!!! Exitement got to me, so I changed the history of the MHLR to closely resemble the HVR, and how it would have been etc. I think this is pretty exiting *note to self, take boat up river, explore old track bed* and I have got to find out more.
I have made a plan from the HVR plan of what exactly the MHLR would look like in the area, and how my extension (not this year!!!) will be justified: http://www.freewebs.com/mhlr/history.htm
