In 1910 there were reports of vandalism on the line. A man named William Morris Griffiths who had climbed Snowdon to see the sunrise, placed a stone on the rail and sitting on it, slid down the track at speed. Someone put a boulder on the line behind him and pushed it down, and it struck Griffiths in the back, he somersaulted off the line and died a few hours later. The manager of the railway also reported that crowds of visitors were breaking down fences, pulling up gradient posts, throwing down wires and interfering with the railway bed.
