The gate is a 250 mm long track which is removed when feeding cars on to the RCB fullbatten track. This is how to do it - remove the gate, line up the short piece of track the car is delivered on and move the car on to the 1100 mm track underneath the gate. When all cars are fed on to the lowest track the gate is reinstalled. 

This kit contains the gate and the 1100 mm long track which is to be the bottom track of the system. It also contain the upper and the lower end stops. The lower stop is made of bronze and comes with an insulating washer to prevent galvanic corrosion. The upper stop is cast aluminium.
