I was "in the industry" in the late 90's.

Two key area's in terms of your cracking issues:
1. The Manufacturing process. Bad process, bad materials, bad design, all can cause issues. The bad ties in the north east from about 20-25 years I think have been narrowed down to bad aggregate and maybe process.
2. Installation/maintenance. This is key to ALL ties, but can really mess up concrete ties. If drainage is not proper and you have a lot of freeze/thaw cycles it can break up a concrete tie quickly. Bad Drainage can shorten the life cycle of all ties.

Thank you very much!

I've found this file on internet about some problems that the amtrak faced with concrete ties a couple of years ago.
The material is very interesting, I wonder if they completed the replacement of all the damaged ties... Any of you guys have the contact of the Alfred J. Cloutier (Assistant Deputy Chief Engineer).

Being in Brazil, it's harder to find informations..
