Hi all, today I present to Alco RSD-16

Built in Schenectady plant between 1957 and 1958, is basically a variation of the RSD-12 model. Its specification is DL-540 model and Argentina was the only buyer of this model. The purchase order was 130 units, of which only now are operating a 60/70 units, the others were radiated or scrapped. The remaining service operate freight trains on the mainline and switches, local passenger trains (Metra type), long distance (type Amtrak) and regional.

Data sheet:

Engine: 251-B Alco 12 cylinder

Vel. Max. : 120 kmh ( 74 mph )

Weight: 108.000 kgs. (238.099 lbs)

Axle: 18 tn

Starting tractive effort: 22,500 kg ( 49.570 lbs)

Continuous tractive effort: 19,250 kg (42.410 lbs)

Brakes: 6-SLAV Westinghouse. And here it make a clarification. Although the original design establishes the air brake and vacuum brake locomotive for freight cars and passenger cars, currently not all locomotives kept the original system. The original system that keep the air-vacuum is operating passenger trains, while the load were modified to stop the air freight cars. This is a result of the modernization of freight cars in the 90s, which received air systems for braking.

You're welcome, nice collaborate on the railfan world.
Would anyone here happen to know if there is a Brochure which is Printed in ENGLISH on the ALCO RSD 16 ? The one I found is not. I'm in need of the PRINTED ENGLISH Version!

Thanks for posting all that! (North American rail fans tend not to know very much about railways in the rest of the world, and there is a dearth of readily available information.)
The Wikipedia article has a link to a data page (en Español, but not too hard for us Anglophones to decipher). A couple of interesting differences from the comparable North American RSD-12:
---weight per axle is given as 18 tons: I assume metric tons, so roughly 40,000 pounds. So the same machinery, marketed to U.S. railroads, would be on a platform at least one and a half times as heavy (per axle).
---traction motors are listed as GE 761. This is a "skinny" traction motor: it was designed for use on metre-gauge locomotives (and has been used on many, many, Alco and GE export units), but in technology is comparable to the GE 752 motors used in North America. Maybe about, roughly, as a first approximation, sort of, at a guess... two-thirds the rating of a 752. But, of course, this is a six-motor locomotive: the same engine (and GE 581 main generator) were used on the four-motor domestic RS-11 (= Dl-701). So spreading its power over six axles (each with a bit under two-thirds the weight) and six motors (each with about two thirds the rating) makes good sense. The 761 was almost certainly cheaper (a lot less copper) and lighter in weight than the 752, so it was an obvious choice for this export design: for, one assumes, the same reasons, it was used in two roughly contemporaneous Australian locomotives, the New South Wales Class 43 (General Electric design, built under license in Oz, with an Alco Diesel engine) and (the first batch of) Class 44 (Alco design, built under license in Oz, with the same 251 engine as the RS-11 and RSD-16).
In terms of performance... the domestic RSD-12, with its much greater adhesion weight and big, 752, traction motors would have been better at low-speed drag freight (so, for example, the Lake Superior and Ishpeming wouldn't have been tempted to substitute RSD-16 units in its iron-ore business), but in passenger and general freight... perhaps about equivalent to an RS-11.
