This thread was born as "Covered Hoppers - for Cement".
Although there have been a few posts on the referenced thread
this part of my question has gone essentially unanswered ...
What I'm looking for is the kind of -general- historical information
that covers questions such as
1) When were cement hoppers commonly in use (as opposed
to the earliest experiments - which I know about )?
2) Was I wrong in my general statements about how far -most-
bulk cement was moved in covered hoppers?
All - I am not talking about concrete - I'm interested in the
bulk cement hauls (before, during, and after the transition to
using 'dedicated service' covered hoppers).
At least one thing I learned from the prior thread was about
the use of "bulk containers in gons" in the early days. Thanks
for that detail/piece of information.
