Dogbert,
Waste Mgt in conjunction with regus rail uses the following cars:
REGX, KRL, BFTX, GSCX, GCCX, SRAX & MWCX.
Currently they do all the C&D off the Bush and are again on the increase 15-20 Cars/ day. You will usually see about two cuts of them on the outbounds due to the lack of power, grade and crossing issues on the branch.
BFI has had a few equipment on Flatbed moves recently which were not at all productive. (as in "Dump the train.....were on the ground in two different places).
There are many pipe dreams in store for the Bush Branch as well, but I will wait to see more evidence before posting.
I joined the railroad to be a trainman and end up being a garbageman
