In the old days, there was a lift point that had a jack lift specifically designed for it. They are still in use, but now almost all trainyards have a forflift for the job. If you notice on the trucks, there are specially made metal lift points/sleeves welded to the undercarriage for the forklift forks to fit into.
Railroad tracks do rust, and this is a major problem in some areas. As the steel wheels of rail cars run over the rails a very small part is worn off due to the friction of steel moving across steel. The wheels of train polish the top of the rail to a shiny surface. On rail that see lots of traffic the rail doesn't have time to rust because of the constant polishing action of trains.
If the tracks are not parallel, the wheels will not stay on the tracks; train wheels are spaced at a fixed width, or gauge, and that width cannot expand or contract to accommodate non-parallel tracks. Thus, if the tracks were non-parallel, the wheel would come off the track and cause a derailment.
Trains are built sort of like cars. They do each piece individually. They will either be built on the track or will be lifted by crane onto the service track that leads out of the complex. *Added - Most train cars (passenger coaches, freight cars) have a body that "floats" on its "trucks" (the wheels, axles, suspension). The trucks are pushed or lifted onto the track and then a crane will lower the body onto the trucks. If a moving train has "derailed" (gone off the track), there are special "re-railers" laid down by workers that force the wheels back onto the tracks, and in most cases, the train can simply continue.
Caterpillar tracks are knobbly strips of metal or rubber, which wrap around the wheels of tanks, bulldozers and other off road vehicles. They stop the wheels from getting stuck in muddy or sandy ground. This is a very helpful technique.
Since the 1870's railroad tracks have been built almost exactly the same. The tie is the wooden beam the keeps the rail (steel usually) off the ground, the rail is connected to the tie with two spikes on either side, and gravel as the base.
No. The mega bloks tracks are more narrow. Mega block thomas trains are designed so that the wheels are about as wide as the 2 by 6 block they are attached to. The LEGO duplo thomas train wheels are set so the wheels sit outside the footprint of the block they are attached to. This makes their tracks much wider than the mega blok tracks. I haven't tried this yet, but you could probably swap the wheels. If you have some duplo trains you won't be using, you could probably take a mega blok train off its wheels and put in on a duplo set of wheels.

you put them on the bottom or you take off the grip tape and them on top
you get a drawer and a saw and cut out the shape then go to a thrift shop and but some old roller skates and cut the trucks off then nail the trucks and wheels in the piece of wood
first you need all the tools as in wheels ,deck trucks and that stuff. you will also need a screw driver and an exacto knife. peel off the grip tape and place it on the deck of your skate board. cut off the extra grip tape from the sides with the exacto knife. you attach the berrings to the wheels and the wheels to your trucks sides. with the screw driver poke holes out of the holes on your deck.use screws to screw a square rubber thing( i dont kno its name) to the holes then screw your trucks on and go skate ! :)
depending on if you have a small bolt or big bolt pattern wheels. the trucks though might have a larger size No. the off set is different.
They should fit 2003-2016
