The performance of glue laminated railway ties after 40 years of service in the main line track
J P Hösli, E E Doyle, C P Bird, T Lee
Two series of horizontally glue laminated ties made of a softwood body and topped with a hardwood lamination were creosoted and installed in 1947 in a tangent and a curved main line track. The tests are now 40 years old and the excellent condition of the ties of these two series suggest that a service life of 50-60 years can be expected.
