Matt: Thank you for the reply.
Now, qu'est-ce que c'est qu'un "intercooler"?

Il semble que ce soit une sorte de mécanisme de refroidissement dont j'ignore le fonctionnement précis. Just kidding!

As I said it'S a kind of mecanical device probably cooling down the engine but I don't no much about it. The intercooler on these locomotive is the mid-sized horizontal louvers protuding near the roof line just beside and up the radiator fan on the long hood end. The Atlas shell is render this detail nicely since you can see the coil behing the mesh.

Wiki says:

"An intercooler is any mechanical device used to cool a fluid, including liquids or gases, between stages of a multi-stage heating process, typically a heat exchanger that removes waste heat in a gas compressor. They are used in many applications, including air compressors, air conditioners, refrigerators, and gas turbines, and are widely known in automotive use as an air-to-air or air-to-liquid cooler for forced induction (turbocharged or supercharged) internal combustion engines to improve their volumetric efficiency by increasing intake air charge density through nearly isobaric (constant pressure) cooling."

Underscoring is by me, I'm curious to see how this apply to a RS10/11/18...

On ALCO, it was just some coil of tubing protectec by a mesh (king of chicken wire). On MLW, a more robust perforated plate was covering the intercooler. Probably to protect it in the same was a winterization hatch works on roof fans.

I guess some other guys here know a lot more than me, it wouldn't hurt to know better what we are modelling.
