Hey! I have a problem. Every time I drive a Southern Pacific Class GS-4 through any tunnel, even if I have the blower on, there is a fatal blowback. So is there anyway I can have this problem fixed?
From my limited research I believe the blower should be on at all times when the locomotive is in steam in real life. However, regardless of the blower position, DO NOT have the firebox doors open when entering or travelling in a tunnel! Hope this helps. https://steamcommunity.com/app/24010/discussions/3/3557193237101963045/
