Guys was a saw a rail grinder this video is so cool that I want to to that lol I like watching this so bad really im not kidding but did it break your camera first of all its a rail grinder it breaks glass
sparks from a grinder have a high temperature, but have very little heat. They don't do much damage. It's like how sparks from a sparkler firework are super hot, but don't burn your skin.
That’s kind of concerning if something like that caused a train to derail if it was travelling at a faster speed while grinding the railway with its wheels
The sparks are really light weight and don't retain heat well it would be like pouring sand on a camera at your feet from about shoulder height (if even that)
