Now thread the required number of chairs on the curved stock rail (check template for number - remember to exclude the slide chairs as these are fitted later and each alternate chair where the check rail will be placed). Then using the Track Template as a guide, gauge across at the switch end and glue the two chairs down (marked with a blue * on the left hand side of the diagram below), then go to the other end and gauge across from the vee and glue the chairs (marked with a red * on the right hand side of the diagram). The other chairs you threaded onto the stock rail are not glued at this stage. Your construction should now look like the diagram below.
