My, what big radiators you have With all of the added emission restrictions over the last couple of decades, the cooling capabilities of modern locomotives demand larger radiators, culminating with some expansive “wings” seen on GE’s latest models like the ET44C4 and ET44AC. Passing older BNSF C44-9W No. 5041 leading a westbound vehicle train at the west end on Montana Rail Link’s Laurel Yard is a BNSF ET44C4 No. 3905 being used as a rear DPU on an eastbound grain empty on October 8, 2023.
