Reply to "Can HO Scale MTH PS3 boards be used in O scale"

Thanks H1000 for that information!  Now I know what to look for!

A fast breaking fuse can provide over current protection.  A Littlefuse 370-0400 has a melt point of .0250 A-sec.  Which means if all of a sudden the current popped up to 1 A the fuse would open in 25 ms.  I doubt that would have time to hurt the electronics. 

Although I have never had a motor stall.
