Gordon's Hill is the steep grade's nickname between Wellsworth and Maron. In 1945, Gordon got stuck on a hill due to the heavy weight of his goods train. Over a distance of eight kilometres (five miles), the railway lines climb over around a hundred metres (two hundred and eighty feet) to reach Maron, a gradient of 1:75 and a severe test for engines on the NWR. When the railway was built, there were strong winds crossing from the sea towards incoming land areas.
Planting trees on either side of the line was an option to do this and leaves were spreaded onto the line as James once discovered in Gordon the Big Engine. Bankers are often required to help trains up the hill and run the risk of being chased by a runaway train - Duck found out the hard way in Duck and the Diesel Engine.
