It's spelled COOLANT...and the block has freeze protection and will dump the coolant (water only on BNSF) to the ground below a set perameter. Otherwise, yes, you'd have to keep the engine idling all the time (in freezing weather) and burn up all that fuel...and what if things went wrong and it COULDN'T be kept running??? Not only would you have a shut down engine for whatever reason, but you might have a CRACKED BLOCK, too! So there ya go! No ethylene glycol because it might not protect EVERYTHING in -30 freezing weather, anyway- plus, it gets expensive over a fleet of several hundred locomotives. Just auto-drain the block if it freezes...
