Anyone who thinks the SD70ACe isn't boxy enough will surely enjoy the new Saudi Arabian variant of that model, which has all sorts of big chunky appurtenances added to it:

Yup, that's boxy alright. What are they all for? Air-conditioning?

My guess is that they're air filtration devices, necessary in order for the unit to cope with the dusty/sandy environment in Saudi Arabia.

Maybe they could have come up with a way to divert that sand to the rail... instead of having separate sandboxes to have to fill ;)

Not a bad idea... I bet GE will use that in their next Middle Eastern locomotive. :wink:

RIYADH: The first consignment of six of the 25 locomotives for the mineral railway line project was received Sunday by the Saudi Railway Company (SAR) at the King Abdulaziz Seaport in Dammam.

"The locomotives are imported from EMD (Electro-Motive Diesels)," Fawaz Al-Magati, rolling stock supervisor of SAR, told Arab News on Monday.

Al-Magati said that the remaining 19 locomotives will arrive here by the end of this year. These 4,300-hp engines will be used for transporting mineral on the North-South Railway.

"They are designed to suit the climatic conditions of the Kingdom and are equipped with pulse and sand filters to travel through desert conditions," said Al-Magati.

Early last month, SAR received 125 of the 688 wagons for the mineral freight line. The locomotives are manufactured in Canada for the US-based company while the wagons are produced by the Chinese CSR company.

Al-Magati said training for the engine drivers and other technicians would start in October. The company's target is to start operations before the end of the year.

"We may do a test run in early November, Insha Allah," he said. "The 2,400-km North-South Railway is given priority due to its important role in industrial development of the Kingdom. It would ferry minerals from mines in the north and central zones of Al-Jalami and As-Zabirah to Ras Al-Zour in the east for processing."

The rail line — sponsored by Public Investment Fund — is integral to planned phosphate and bauxite mining projects in the north of the country that will link up with processing plants and smelters on the Gulf coast.

The new railway would transport 15,000 tons of minerals in a single trip, the equivalent of 600 cargo trucks. Al-Magati said each locomotive would pull 100 wagons.

Thanks, Charlie!
I've seen other photos of these locomotives, but I think the one in the article you link to is the first with a clear view of the rear of the long hood. They are basically SD-70 (SD-70MAC?) types with (like earlier Saudi locomotives) mammoth air intake sand filters on the roof: Saudi Railways don't seem to have many tunnels or close clearance over-bridges!
There are also a pair of hexagonal objects mounted along the handrail about above the front and back of the rear truck. External sandboxes, like those on Union Pacific DD-35 and DD-40?

The model designation for these locomotives is D70ACS.

The boxes are indeed air intake sand filters. EMD, and I'm sure GE has a spec for the sand used on their locomotives. You just don't go to a beach or desert and shovel the sand into the locomotive supply boxes. I recall silicone content was 1 of the spec requirements for EMD.

Air intake filters appear to be standard in Saudi Arabia. They even had F-units (retro?)fitted with them.
Mauritania uses similar designs:

Air intake filters are, as you say, standard on Saudi EMD locomotives. I think they have all been factory-fitted, not retrofitted: an old "Trains" article on EMD exports, reprinted in the (I think out of print) Kalmbach book "Our EMD Scrapbook" had a photo of F-units for Saudi Government Railway and Alaska Railroad side-by-side at La Grange, the Saudi unit already with its "schnorkel".
