Question

How will turn the train engine wheels in curved track..plz explain?

Answer 1

the wheels are fixed to the track & cant be removed easily.............so as the track changes or turrns it just moves b'coz of newtons laws

                                      - hope u understood my explaination

Answer 2

Train wheels use a pivoting axle system on the front and rear. Train cars use them as well. If you notice the shape of the wheels, the inside has a lip that sticks down further than the rest of the wheel. This lip rides along the inside of the rail. As the train comes to a curve, the lip directs the wheels along the curve and the axles turn on their own. Hope this helps.

Answer 3

Locomotives have something called a swivel truck to help them on curves this was developed in the 1850's and it worked wonders. It prevents derailing so trains won't fall off the track from their own weight.

Answer 4

Train wheels has a pivot axle setup on the both front and back . Train compartments use the same system. This lip rides along the inside of the rail, when the train comes to a curve, it directs the wheels along the curve and the axles turn on their own.

Answer 5

Most trains use trucks with two axles and four wheels that piviot on the engines chassis. Each truck has brakes and powerful electric motors.

Answer 6

First, realize that curves on a railroad have a much wider radius than roadways so the wheels dont have to turn as sharp.

As you have observed, the axles are solid and there is no "differential" action as there is in automobiles and trucks.

Secondly, the axles on a railcar are mounted on a subassembly called a truck in the U.S. (or bogey in the U.K)., this truck pivots seperately from the railcar and follows the curve, bringing the car along with it.

Train wheels are very slightly tapered so as they go around curves they are able to negotiate the turn.

If you sit near a sharp curve on a railroad, you will probably hear the steel wheels squeel and shriek as they go around the curve, this is the wheel flanges rubbing on the rail. there is some friction of course but it is minimal.

There is not nearly as much friction between steel wheels and rail as rubber tires and pavewd roads, that is the reason trains are so much more efficient than trucks.
