Probably the biggest difference between rail systems is the use of
concrete ties in Europe. In the USA, we use a crushed limestone base
with wood ties. The rails are assembled in sections with the ties
attached and then put in place as a unit. In Europe, there is usually
a concrete base with a cushioning pad of some form, the concrete ties
and then the rails attached to them. I don't think the European system
allows for section placement.
Each method has advantages, but I believe the wood tie system works
better for bulk/freight and has less maintenance issues.
