I think the standards we're working with right now are pretty good. I think we see fewer and fewer sun kinks. We have welded rail now, and it's being de-stressed, so we see less of that. Broken rail is still a problem when it's very cold, minus 35, minus 40. A lot of the railways do have special instructions now. When the weather is below a certain degree, they will reduce track speed.
So I think from an inspection standpoint, it's pretty accurate right now.
