Yes and they work great....it takes time to install them. What I ended up doing, was setting up one of the turnout's with the ground throw attached and setting them on a piece of paper and marking the turnout and the location of ground throw mounting holes, on to the paper.....need to make sure that the ground throw arm is at 90 degrees to the turn-out. This pattern become the guide for placing the ground throws on the layout. If you are using foam for your base (foam mounted on plywood), the ground throws can be easily and securely mounted by using a glue called GOOP (hardware stores, hobby shops, etc. have it). When mounting the ground throws, make sure the control arm of the ground throw is level (a very very small bubble level works great).
