I'm seeking info on Fire Bricks, these were used by trains that ran the Virgina Creeper Trail over 100 yrs ago

I recently found some of these bricks and was told that trains used these along the Virginia Creeper Trail (over 100 years ago)and that they were often tossed out over trestle bridges into the water below. They are pourus and off-white in color, some were rounded due to tumbling in the water and some have stamps or words that can still be made out. I also found a few red ones that were the same as the others except for the color. I would like to find all the info I can on this, whether it be info that anyone has found themselves or sites/links that can guide me to the information.
