Do Engines have ACI Data Plates?

@Ron045 posted:

I never noticed this in the past but this photo of Chessie B&O #7619 looks like it has an ACI Data Plate mounted on the handrail.  Was that normal?

Yes, back in those days (whenever that photo was taken).  Also, "engines" did not have ACI labels, but "locomotives" did.

In the next photo its sister engine #7618 does not have the placard?

Depends on when the photo was taken.

Or is this some other type of placard?  Any insights would be appreciated.

You might try a Google search for "ACI Labels" and when they began and ended.

Thanks!

I get the distinct feeling there is a terminology lesson for me above.

Thank you.

ACI plates came into railroading in the late 1960's and lasted up into the late 70's or in some cases the early 80's.  Only certain railroads adopted this system.  The technology has since been surpassed as the data plates got dirty or damaged which interfered with reading them properly. 

As to locomotive terminology to some it's 220/221, whatever it takes.  Technically there is not an "engine" per se in a locomotive.  The prime mover is the diesel fueled powerplant that provides electricity to the traction motors that power the wheels.  A totally different topic however.

As I recall, the ACI system was used by most of the roads that eventually merged into CSX.  ATSF used the system as well.  What other roads used this tracking system?  Cars also had data plates as well.

No, just him being his usual ***..

I have these decals I used on some freight car repaints I did.

Guess since I'm modeling #7619 "Locomotive" 😉, I'll just have to figure out how to mount them.

Thanks for all the feedback.

I do not know if this is true.  But I read the KCS had this oddly painted locomotive for the bicentenial.  The colors were such that it caused a trackside ACI to malfunction.
