After they build a train how does it get on the tracks.is it built there?
Rolling stock is built then placed upon the trucksThey are not attachedThe weight of the car keeps it on the wheelsLocomotives are usually built upside down, doing the work that will be under the loco firstAfter all is done below the frame, it is turned over and the other elements of the locomotive are addedRe-railing derailed equipment is a different storyIf a car has dropped at set of wheels, if minor and remaining close to the rails, blocking material, consisting primarily of wood blocks and chains, can be placed to walk the derailed wheels back on the railThere are also two types (the Budda and the butterfly) of large steel devices called frogs that may be necessary to walk a heavier car on, or even walk a locomotive truck back onIf a car's truck has been turned, yet still near the rail, as the car is pulled on, a slewing cable is attached to turn the truck as it moves, with the other end tied of to a tractor or some other kind of heavy equipment to align the wheels to the rail so the truck will throw onWhen cars are semi-scattered, a hi-rail, 200 ton crane is employed when heavy lifting is neededThough there are still some steam derricks left, their use is infrequentI have seen these new wonders suck an SD-45 right out of the mud, one end at a timeWhen there is a major pile up with cars scattered all over the place, they bring in the big Cats and they just shove the stuff out of the way to get the line openThese cars are usually cut up for scrap on the spot.
