Here is Salt Lake we are starting to see cars more frequently with reporting marks "TFM." I thought KCS de Mexico bought out and replaced TFM. Is this not correct?
TFM was created in the mid-1990s to privately operate some choice routes in northeastern Mexico. KCS purchased a large block of TFM stock, but there was a dispute about the actual ownership of routes in Mexico. In 2005 TFM was renamed KCSM. You'll probably see a lot of TFM equipment rolling for years to come, painting is not a high priority.
