1933 rail detector car

Here are some photos of a vintage 1933 rail detector car labeled X-101.  It was apparently sponsored by the American railway Association.  There was little information on this detector car provided.   I believe the first unit was the power and the second unit contained the detector equipment.

This detector car would make a really neat model

I am busy building my welding shop and the steam shovel kit.  Photos probably later this week.
