As this system of levers is placed uponeach side of the truck, and the verticallevers like F, K, etc., are attached directlyto the brakeheads, there is no need ofthe ordinary brakebeam, but, in its stead,simple flat tie beams are used that serveto hold the brakeshoes in place and haveno braking stresses put upon them. This system of brake levers . has beenthoroughly tried and can hardly fail tobe as effective here as it has been else-where. In the construction of these cars theVirginian has followed along the lineslaid down at the ti-ne it was built, namely,the handling of the heaviest possible ton-nage from the mines to tidewater, in carsbuilt especially for the traffic which would remain
