As the systems become more "chip" dependent, they become more temperature sensitive. The cooler the better.

Seems to me recent model CN and CP locomotives don't have heavily tinted glass!

Or you will be sorry. It is legal to have the back windows fully tinted of an SUV, and I went with a 20% for the front windows on some of the trucks.

For "attack protection," check 49CFR Part 223 relating to requirements for locomotive glass (glazing) - Type I and Type II. Your library may have the CFR's, or you can find it on the internet. It's interesting, revealing reading.

The windows are large compared to what would be visible of the crew. If you can't see them, you're a little less likely to get lucky and hit them. And the bozos who would shoot at train crews probably care little about the NRA, or anything else but their own amusement....

Reply tnchpsk8 Member sinceOctober 2003 31 posts Posted by tnchpsk8 on Monday, July 18, 2005 8:25 PM My bet would be as a heat deterrent. Having been a long-haul trucker for thirty years, I would put aftermarket tint on the side and rear windows to block out some of the sun's heat therefore letting the a/c work better. As for CN and CP not having tint on their windows maybe both companies feel that with the "cooler" temps in Canada they don't feel it as necessary as locomotives traveling through the South and Southwestern states.

CN has never been a company to 'splurge on the extra's' . ever notice how annoying the sun can be when its coming in the side window? either burning your arm off, or right in your eye where the sun shade doesnt cover. My guess is the tint is an added comfort for crews Reply Edit UPTRAIN Member sinceJune 2002 From: Independence, MO 1,570 posts Posted by UPTRAIN on Monday, July 18, 2005 10:41 PM QUOTE: Originally posted by dharmon QUOTE: Originally posted by kenbowes As long as all you live in a country that holds gun ownership as sacred I'm NRA and I vote.

Pump Reply Anonymous Member sinceApril 2003 305,205 posts Posted by Anonymous on Monday, July 18, 2005 10:47 PM The sad truth is, the dark windows and air-conditioning isn't for the crews benefit. The new A/C engines have a huge amount of computers and sensors onboard. If allowed to overheat reliability and fuel economy would suffer. Where I work on the UP you NEVER saw an air-conditioned switch engine. Then come the remote control locomotives (RCL's). Virutally the entire fleet of them is now air-conditioned. All the better to cool off the computer that's doing my job. Of course, I'm not bitter... Reply Edit edblysard Member sinceMarch 2002 9,265 posts Posted by edblysard on Tuesday, July 19, 2005 5:44 AM The sad truth is the A/C is for the crew...Santa Fe was putting A/C on their locomotive long before computers.... The "computer" for locomotives are located in the nose compartment, in a rack in front of the engineer’s seat, and in the electrical cabinet on the rear wall. If you have ever been inside an AC4400 or a SD70Mac, with the front nose door and the middle crew compartment door closed, you quickly realize it can get well over 100 degrees in the nose...the A/C has nothing to do with the computers, (really fault code chips, very much like what has been used in the automotive world for decades) but for the crew. If the A/C was for the computers, they would run ducts to the electrical cabinet and the nose compartment, both of which have none. What do you guys think happens when the prime mover's auto start/stop kicks in and the unit shuts down for fuel savings? It gets hotter than blue blazes in the cabs all the time. I have been in some that were so hot you couldn’t touch anything metal, or sit in the seats until the A/C had been run for a good while. Quentin, the cabs are insulated both for comfort, and sound. There is a FRA max decibel rating for the cab, both at idle and full throttle. Some of EMDs locomotives have the cab isolated from the rest of the body and frame to reduce both noise and vibration. The windows are tinted to reduce both the glare, and the heat in the cab. Note on UPs leased units from CEFX, the cab roofs are painted white? This too helps reduce the heat transfer from sunlight. The windows are not bullet proof, but bullet resistant, and meet the FRA glazing strength requirements and the FRA shatter resistant requirements. CSXengineer already told you that small arms fire wont come through, but a medium to large caliber rifle can punch a hole in the windows right quick. The tint helps in this also. Oh, and the tint helps keep people on the outside from seeing the engineer use the mirror to fix his hair!
