Sadly, I am sure that is not the only place that happens....they just got caught.
When I worked for the G&O, we had a lot of company owned boxcars we used on the LXOH. It was always nice to get a big fat repair bill from another RR or contract company outlining repairs made (Brake shoes was the biggest line item) and then go back to our own records and note that we had already made those repairs, and sometimes just days apart....
