How does GE build Locos that withstand the Sahara Desert>

I wonder what a "dessert sand" tastes like?

The switcher type car body permitted installation of Roto-Clone air filters, installed forward of the electrical equipment cabinet to keep the entire engine compartment (including the electrical equipment cabinet and traction motors) under a positive pressure of filtered air to prevent the intrusion of dessert sand."

easy answer, they don’t. Those are EMD products in the video. they operate customized SD70ACS, SDL40 and GPL15 models.

I think the older locos are SDL 50s, not SDL 40s.

New locomotives to this design were built until quite recently. Clearly they didn't have the problems of the standard SD50s.

An earlier generation of 'Sahara-resistant' diesels came from Baldwin:

This was in the days before GE or others adopted the idea of the pressurized carbody. These used large Roto-Clone separation and filtration of sand out of the air (see detail pictures).

You would think that the sand would grind most of the componets to a halt.
