Cabooses are still used on Work Trains. For example the Tie Gondola Work Trains on CN’s GTW lines in Michigan have Detroit, Toledo & Ironton Extended-Vision Cabooses.
In the 1990’s the Grand Trunk Western had cabooses on the Local Freight Train from Battle Creek to Kalamazoo’s Kilgore Road Yard. Since the GM Steel Body Panel Stamping Plant and several Paper Mills have closed, that local train now has too few
cars to need a caboose for the Train Man.
On the GTW Main Line Cabooses with crews could be seen on the end of GTW Manifest Freight Trains until 1995.
Long distance Intermodal Trains all had the End of the Train Device’s by 1990.
I did see an Eastbound BN Unit Coal Train with a BN Caboose in 1998. It was strange since long distance unit trains typically have an End of Train Device.
Atlas O has the Twin-Stack Intermodal Cars and the Coalveyor II Coal Gondolas which would more likely have an End of Train Device than a caboose on the rear.
