QUOTE: Originally posted by trainfinder22 The best way to not a crash is to prevent one. CTC and real time dispatching systems using GPS to tell the tower where the trains are at all times means that passenger and freight CAN run together

QUOTE: Originally posted by martin.knoepfel european freight trains are quite short, because the screw couplers do not allow for heavier trains. otherwise, you have to cut in additional locomotives (radio-controlled). unfortunately, the euro-coupler was never introduced although it works. in britain, they run some freight trains (stone) at 100 mph, I guess, to avoid delaying passenger trains. the germans run some freight trains at this speed to on high-speed-corridors. the french have trains with refrigerator-cars (fruit and vegetables) for 90 oder 100mph.
QUOTE: Originally posted by trainfinder22 American Railroads can build cars with Aircraft alnummun and contruction. They can use Polumers and light weight trucks to save fuel and increase speed...But the FRA wont let them because of crash standerds that are outdated..
QUOTE: Originally posted by railman QUOTE: Originally posted by oltmannd I'll add just one more item: Welded rail + tangent track + 3 pc frt truck (and 1:20 tread taper) + high speed = truck hunting = derailment! You can sneak up on 80 mph with some intermodal equipment, but, if you want to go faster than that, you start needing some better suspension. Amtrak's Roadrailers use swing motion trucks, for example. For "regular" freight cars, the truck hunting threshold speed is much lower - much past 60 and you're looking for trouble. Conrail once tried what was really a pretty slick move - moving empty mill gons back from Chicago to Buffalo on the head end of TV11. It saved about two day's transit. Unfortunately, the empty mill gons with worn wheels would become unstable at speeds just over 50 mph and there was a large derailment just east of Cleveland. In the jointed rail days, truck hunting wasn't a problem because the slight irregularities at the joints stopped the instability from "building up". And they called it progress!

QUOTE: Originally posted by Grinandbearit Kevin ! Even though the CPs AC4400CW have 75 mph gearing, I doubt very much if they get up to that speed, and Vias F40s have max gearing for 95mph and while P42s are 110mph ,they never will attain that on CN track with even with the banking on the LRC cars.

QUOTE: Originally posted by Junctionfan Don't they seperate containers and trailers before Chicago. If you only load containers on certain designated well cars, than it would be easier for Chicago to just simply hump the well cars. Seperated the Los Angelas bound cars from the Seatle bound cars. Is there any way that the railroads could do that quickly?
QUOTE: Originally posted by y-back guy Correct me if I'm wrong, but I believe that a freight train that has all articulated cars can do the same speed as a passenger train is permited to around curves. I remember reading that somewhere. Whether it was a true statment I'm not sure. I also believe that Santa Fe had or attempted to run fast piggy backs at 79 miles per hour with a few locomotives which were re-geared to achieve the higher speed. Correct me if I'm wrong on this. I'm interested to know. I seem to remember reading something on this.
QUOTE: Originally posted by M.W. Hemphill For one thing, five-well double-stack cars don't hump properly -- they're too long. Hump retarders only grab two trucks at a time. The technology of a hump yard is inappropriate for the technology of a double-stack car.

QUOTE: Originally posted by trainfinder22 its not that US RRs cant do more then 59 its that the FRA wont let them exeed that limit
I tried to sell my two cents worth, but no one would give me a plug nickel for it.

QUOTE: Originally posted by Junctionfan I don't think Iran will get the ICBM at all because if the U.S does attack Iran, Isreal will. I also have a strange feeling that India won't let Iran have them have it either. Although Pakistan and Indian hate each other, they both know that a nuclear battle would do more harm than good. India has a president and Pakistan has a military like government. Iran how ever concerns me because the whole suicide bombing thing that thease Muslim extremest governments, supposedly is a big thing with Allah. I would have to read the Kuran on that because it sound like a twist of words to me. At any rate that is how they contrue their beliefs and so why wouldn't they nuke someone. If they got nuked than they go to Allah so you can see why we need to me more concerned with Iran than with North Korea. If the U.N is not going to do their job, than the U.S and Isreal who would also be on Iran's hit list; will have no choice but to attack long before a missle system would be needed. Besides why do we need another missle defence system? What's wrong with NORAD?
