With the more flexible springs on 18.EX., and a full load, we had a bad axle bump on a railway crossing which sounded too harsh. This suggested to me deeper rubbers even if they touched more often. The small bumps would not be felt and the large ones would not be so bad. Also I noticed on examination that we are using different rubber buffers both in design and size. These should all I think be of the newer type. I suggested some time ago a sheet metal case like P. 2. front. Probably we may need 2 sizes, and perhaps 2 depths of rubber for each, but all should be of the same pattern, and have the maximum thickness of rubber possible. The Exp. Dept. can try this idea.
