“Shock-absorbing” Goods Wagons

“Shock-absorbing” Goods Wagons.

Rough shunting is an affair which all concerned in freight handling seek to guard against. On the L. M. & S. Railway, a batch of one hundred “shock-absorbing” goods wagons of 12 tons carrying capacity is being constructed, which may ultimately revolutionise goods wagon design. In principle, the body of the shock-absorbing wagon “floats” on the chassis by means of an ingenious springing arrangement, shock-absorbing buffers affording additional protection. Two sets of horizontal, indiarubber springs form a buffing arrangement between the wagon body and the chassis on which it rides, four sets of horizontal rubber springs attached to the chassis acting in the same manner. The effects of any longitudinal shock delivered to the wagon are largely absorbed in compressing these springs, and to that extent do not reach the body and the load. The body is supported and connected to the chassis page 18 page 19

by four slides, which allow of longitudinal movement, but prevent lateral or vertical movement of the body relative to the chassis. Tests conducted in connection with the movement of fragile traffics have demonstrated the material superiority of the special anti-shock wagon in eliminating or minimising the risk of damage to goods in transit.
