LONG WELDED RAILS IN THE U.S.A.

Experience to date with continuously-welded rail has revealed the following facts: (1) A sound practicable welded joint can be made. (2) Welded rail in long lengths can be transported and installed readily. (3) In the climate of that part of the U.S.A., welded rail should not be installed at a temperature under 60 degrees. (4) Welded track can be surfaced, lined, and otherwise worked without risk when done at a temperature equal to or less than that at which laid. (5) There are fewer failures in welded rail than in jointed rail. (6) Proper superelevation must be maintained on curves for the type of traffic handled to secure the maximum life of the rail on curves. (7) It is practicable to transpose welded rail on curves to increase rail life. (8) It appears that a less expensive fastening for welded rail is possible. (9) Difficulties experienced with continuously-welded rail can be eliminated by proper construction and maintenance. Considerable statistical data are included on costs and number of welds.
