 Another guard rail was erected around the inner edge of the track, at a height calculated by Moskovics to coincide with the wheel hubs of racing cars, and a second rail was erected just above the first to arrest the tendency of cars to overturn.While the racing facilities were being built, Pacific Electric Railway constructed a special track spur to deliver spectators via Red Car trolley.Due to the raised outer rim of the circular raceway, viewing was completely closed off from outside the grounds.
