I believe it is an Automatic train stop motor / generator.

I cannot find a model source for it at this time.

Christian, it looks like the ATS Generator for the ATS Shoe on the front truck. This part is available from Custom Finishing #208.

Note also the ATS shoe mentioned by one or two people above (looks like a funky brace below the bearing for the first axle on the front truck).

I do believe these two things are related; pretty sure I’ve seen detail parts for these from either Details West or Details Associates. Having no particular need for these details as the railroad I model never used any form of ATS, I’ve not looking into this very closely.

Yes it is Automatic Train Stop equipment. I use the Custom Finishing part mentioned, as well as the shoe on the first axle. I also use the ground mounted inductor that passes the signal to the ATS equipment on the locomotive, along with a small junction box. It makes for interesting wayside details. ATS would apply the air brakes if the engineer passed a signal that indicated stop, and then he had some splanin to do about why he ran a restritive signal aspect. There was an electrical cabinet on some NYC locomotives, such as the one in the same location on the following Pennsy unit. Some NYC units had the other components hidden from view with no ancillary cabinet, and some had the cabinet. They were also applied to steam locomotives, but the pick up shoe was mounted on the tender trucks, with the equipment box usually up by the water hatch. There is a little round gizmo mounted on the frame, directly under the 4 in the unit number, with a flexible cable going down to the shoe that is also part of the ATS.
