How many times has your model railroad crossed over a grade (roadway) crossing and you had to hope no automobiles were getting across the tracks? Well rest easy model railroad train engineers, you trains won't hit anything if you have these across the road. I have one on my main tracks and it works when I power up that track section as I placed two red Grain of Wheat Model Power bulbs into the signal lamp holders. It works great and stops traffic while I running trains. Have fun, and like me, get more than one!!
