This is my interpretation of Sodor. A map I made for my son. I wanted it to have more detail around landform, urban areas and roads. Mostly it follows the many maps that have gone before, except where I found things illogical or contradictory to things I had seen or read.
For example - The Sodor Search and Rescue Centre is mostly shown at the top of Suddery Bay (an area depicted on the original maps as swampy). The TV series always shows the centre backed by high rocky cliffs. It also seems to me that Misty Island must be close enough to be reached by tunnel of reasonable economic length. This is also a problem if it is in Suddery Bay. I have also changed the mainline loop to go back to Cronk/Killdane. This is so I could get a line from the Blue Mountain Quarry to Brendham Docks to get the stone and slate to the ships.
I have also moved Brendham up the bay a bit to make it more sheltered from the open Irish Sea. Finally I have the airport next to Brendham because one of my kid's books puts it there when Percy and Harold race to Brendham.
