Just being my usual self. ^_^ Probably from dragging stuff or wheel/brake sparks. Under normal use the wheels get very hot. Never seen an axle sieze but if it did that would drag steel on steel and make one hell of a lot of sparks. -- DougW |

Most of this area is flatlandia so the trains don't brake so drasticly. I'd suspect areas with steeper grades that wheels/brakes sparking could be a real problem. -- DougW |
