What the &$#@ is air conditioning?
the new units have it, some western roads had roof mounted units, but by and large, A/C is only a dream, on the railroad. (unless you got one of those office jobs) Side windows wide open, back door latched open (no latch? Just stick a broom, or flag through the door handle, behind the handrail) and if you are travelling below 30 mph, pop open the front door. "Instant A/C". Of course, it's against the rules, on some properties, but when it's 140 degrees in the cab, who gives a damn about the rules, anyways? A really fast way to "sweep" out the cab as well. Secure all of your paperwork, put your grips against the front cab wall, and open the front and back doors, while travelling 50-60 mph. No dust, dirt, or personal belongings, that weigh less than 5 pounds
As far as a hood door open, that's just a lazy engineer, or trainman, not doing their job. Every rulebook, TH&AB etc., has a rule about not operating with open hood doors. The engine compartments are pressurized, so by leaving a door opens, you defeat the purpose of a pressurized carbody. Sad fact is, most guys just "get on and go", without even the most basic inspection, or look around the equipment, being performed. I know of no crew members that would go so far, as to "ruin" your photos, by propping open doors. Some will extinguish headlights, but they are actually trying to help you, so the lights won't mess-up your pix. The "purists" want them on, so it looks like a moving train, but hey, what does an engineer know about photography, anyways. (unless he is RCBSD-45
) They aren't trying to kill your shot, perhaps a misguided attempt to help you. Regards
