White and Black Smoke

[NW Mailing List]

I remember reading somewhere that the railroads could be fined if they
produced excessive black smoke in populated areas; a "smoke density" chart
was used to gauge the extent of the violation. Does anybody know more about
how that worked or any stories of "repeat offenders"? I remember reading
somewhere that you never wanted to leave Roanoke past the N&W office
buildings with black smoke because you might get spotted by the president of
the N&W and really catch an earful.

Good morning.

 

I am not worried about my Arrow not arriving yet and will not be posting
when it arrives.

 

The purpose of my post this morning is to inquire as to why on many of the
programs that I watch on RFD TV (Trains and Locomotives) some of the smoke
is black and some is white.  What is the cause of this? Have a great weekend
and thank you in advance for any responses.
