I had not thought about this for years, but this topic prompted my aging brain to conjure up some memories. GP30's were the first Santa Fe units from EMD that were built with centralized air filtration and pressurized carbody. The idea was that slight pressurization would keep dust and dirt outside, and, normally, it had a positive effect.

However, if the filters became clogged, the fan still took in air from wherever it could obtain it, and the cab compartment appeared to be ideal for this. In winter, when a GP30's filters needed to be changed or cleaned, the cab heaters could hardly make any difference. I have seen my breath in the cab on more than one occasion. Imaging ascending Cajon Pass for over an hour, in Run-8, with the centralized air filtration fan sucking winter air into the locomotive via the cab. Brrrr.
