Well, the smoke fluid is loaded into the side for the main smoke stack, it only gets to the whistle side under the baffle that separates the two sides of the smoke unit. The arrow indicates the baffle plate, and the red line across the smoke unit bowl is where it slides into the smoke unit to separate the two halves. So, if there is enough smoke fluid in the stack side, and the locomotive is tilted 30-45 degrees toward the whistle side, the fluid will eventually migrate into that side.
You don't lift the front, you tilt the locomotive do one side, and truthfully I don't remember which side is the whistle smoke now.
