Publisher's Synopsis
Excerpt from The Varieties of Permanent Way, Practically Used, or Tried, on Railways Up to the Present Period: And on Some Recent Improvements in the Permanent Way of Railways
In the United States, the battering of the ends of the rails in the chairs is so excessive, that an india-rubber bearing is said to have been adopted with great advantage. A continuous bearing of cork has also been laid experimentally, for upwards of two years, under bridge rails, on one of the metropolitan lines, to pre vent vibration on girder bridges. - W. B. A.
