The Locomotive Fire Ring

Since Delmar first had a fire department they have always had a fire whistle to sound the alarm.  Originally it was steam and was operated from the train yard. 

Some towns however have used a "fire ring"  that when hit with a hammer will provide the noise to alert people there is  fire.

These fire rings would be made from steam locomotive metal tires that were originally around the drive wheels of the locomotive. When the train wheel tires wore out and were replaced instead of scrapping the wheel they recycled it at the local fire department to be an alarm.
