I would agree with Blaine here. The track most likely is not in a stress free state. Meaning for some reason the RNT has been lowered. A verse test could help deter mine that non destructively. Another approach would be to install a wireless and ...

Great information, Anamaria! Thanks for sharing! Was there ever a formal write-up of the data - i.e. rail temp by date and time for painted and unpainted sections - and presentation to a professional group such as AREMA? Would be an interesting discussion. ...

Hi Anamaria, Very interesting approach to mitigating thermal misalignment concerns. I noticed that, at least in the photos you provided, that MNR uses rolled plates with elastic clips as rail fastenings. If you are having issues with thermal misalignments ...

MNR did a rail washing test program with a high-pressure wash before applying the paint, but it didn't make a difference (see photos). The reason for needing a recoat is the rust from the rail head bleeds down the web of the rail and turns the white ...
