The floors over the basement were designed to carry 20-ton cars and for this reason were rather heavily rein-forced. They are supported on concrete columns 18 ins. verse beams, and are reinforced with }l-in. rods placedat right angles to the tracks on 10-in. centers. Thepit walls, 9 ins. thick and 45J/2 ins. high, have re-inforcement at the bottom and serve as longitudinalgirders.
