Hol - Thanks for confirming. Would you care to venture "why" a suburban service 4-6-2 was so equipped? Particularly since 2838 was one-of-a-kind. It would've been expensive to retrofit such a locomotive with cab signals. Could it be, as I posed earlier, a test bed for the cab signal equipment that was installed on the Class O-5 and Class S-4 locomotives? Or, was 2838 needed for "protecting" certain main line passenger trains on the Chicago/Aurora Divisions? Anyway, for those modelers in our Group, now you have a basis for a cab signal equipped suburban service 4-6-2! Best Regards - Louis

I checked assignment sheets, and 2838, assigned to the Chicago Division, first shows as being equipped with cab signals (which is what the box is for on the S-4s and O-5s, plus a good many Geeps -- not ATC) in February 1952 and continues to be listed as such through February 1954.  In March and April 1954 it is listed as condemned and it is gone from the assignment sheet in May 1954.  So that answers the question as to what the box is, but it shows that the disposition date in Corbin's book is wrong; it shows 2838 as sold for scrap in February 1951 (not 1952), when in actuality it was not sold until April 1954.

Group - Can anyone further identify the following inserted and attached undated image of CB&Q Class S-1-A 4-6-2 type No. 2838 taken at Downers Grove, IL, while in suburban service. Is that an Automatic Train Control (ATC) box mounted on top the boiler?

 

 

I've never heard of ATC being applied to "smaller" steam power such as 4-6-2 types, particularly to those in suburban service. We're all familiar with ATC boxes that appeared on top the boilers of Class O-5 4-8-4 types and Class S-4 4-6-4 types. If this is not an ATC box on No. 2838, then what is its purpose?

 

If indeed this shows an ATC installation, then, perhaps, it was a test bed for what equipment was installed on the Class O-5 and Class S-4 locomotives. Too bad the image is undated. The two-tone suburban coach behind the locomotive might help to date the image. No. 2838 was sold for scrap in February 1952.

 

Comments appreciated. Best Regards - Louis
