This noise is not coming from the fans, as someone has said, they'd blow apart long before they'd ever make a noise like this. I thought it was the fans for the longest time too, it is absolutely not natural for a locomotive to make that much noise. Also if it was the dynamic braking fans, you'd surely hear this in all the units, but it is very clearly coming from the auxiliary locomotive, not to mention both engines are running wide open. What it most certainly is, is a turbo fan that is off balance, could be caused by anything ranging from shot bearings, carbon deposits, or just a damaged blade from wear and tear. Ever used a Dremel tool with a small cutting disc? Ever turned the RPM too high and noticed a heavy vibration with an awful loud noise? Imagine that, but with a giant turbocharger, bingo, that's your noise.
To say it in layman’s terms it is a mechanical blower that pushes air into the cylinders. 12 16 or 20 645 or 710 engines… Because the engines are a two stroke diesel they have a compression and a power stroke and the intake air charge must be forcibly input into the cylinders and forcibly ejected so therefore it is a blower or compound turbo supercharger that provides the push and scavenge of exhaust gases… Aka a Roots Blower on the old 567s
CSX 5284 used to have this Horn called Narrow front K5HLB Types: 1L 1 2 3B 4 But Basically in 2012 it was Caught in a Derailment In 2014 CSX 5284 was Repaired with a Special New K5HLB Horn called Raise Letter K5HLB Types: 1L 1 2 3B 4 So Basically I will tell you some Trains with it Here are some Trains with Narrow front K5HLB BNSF 5459 BNSF 5846 BNSF 7606 (Replaced with Normal 3) BNSF 7607 BNSF 7608 (Replaced with Normal 3) BNSF 7707 (Missing a 1) CSX 5288 CP 8705 (Replaced with Normal 3) Here are some Trains with Raise letter K5HLB BNSF 8025 BNSF 8026 BNSF 8052 BNSF 8055 KCS 4817 (special 3B Type Got fouled) KCS 4818 KCS 4834 CSX 5284 (Modern K5HLB) CP 8706
really sad, as a ex CCP employee to see my former company take 577 slow orders in 1985 and rehab almost all the mainline....leaving 17 slow orders in 1995....then see CN come in and just abuse this line....im sure my EJ&E friends will back me up on this....traveling to elgin a few weeks ago i a parked my car to close getting stopped by a CN train....i removed my seat belt and opened my door, after the first 30 cars or so i got out of my car and was ready to run....same to say when mom and i were stopped by a train at armytrail road....i jumped out of the van and was ready to run....CN is a poor excuse for a railway...
