Reporting marks

Can anyone tell me what the evxx reporting marks stands for. It was on two 89’ flatcars with two large containers on each car and each container was covered with a tarp. If anyone knows what this mark means and what the cars hual, i would like to know. Thanks

I haven’t heard of, seen, or been able to document, reporting marks EVXX.

I suspect that you may have seen some of the flat cars lettered ECXX, operated by ECDC Environmental (previously the East Carbon Development Company).

It’s been a while since I’ve seen one of these cars, but I believe those tarp-covered containers carry some sort of low-level radioactive waste–either contaminated soil (“dirty dirt”) or other contaminated substances.

Most of the time the dirt is carried in gondolas (also covered by tarps); I don’t know what the advantage of containers would be, except for the possibility of loading them at a site not served by a railroad.
