Quite the 2-man harness. Wouldn't want to drop one of them on yer foot.

Seems like many countries are going to concrete ties as they are improving their rail systems. Made me wonder about the composition of that concrete, so I had to look it up.

Very informative. Thanks for the links. They indicate these are 'pre-stressed' concrete ties. Which I would presume to mean an internal pre-stressed steel reinforcement of some sort. (Like pre-stressed concrete floors of a high-rise.) Though I didn't see any elaboration concerning their definition of pre-stressed.
