While I was looking for repack/lube markings I noticed
something about almost all of the tank cars that I don't
remember hearing talked about before/knowing about.
Almost all of the have the reporting marks on the frame -
as well as on the left end of the tank.
Is that so they can be identified when the tank leaves the
frame during a wreck? Something else? Is this a 'standard'
and if so when was it introduced and/or repealed?
