BlvWhy the Railway tracks dont have banking? The Rail cannot slow at turnings also without banking? How is it possible?

Yes, they do have banking, very subtle.
You haven't noticed yet.

Interesting question! Yes, they do have banking; but just not as 'visible' as on regular roads. I think that's also because of the design of the wheels of the railway track. The inner portion of the wheel is lengthier than the outer one; which helps counter the centrifugal force.

Totally agree with the admin...The shape to the wheels f the train, makes the train to make a centrifugal force while taking a turn on the railway track. To solve the problem of banking of railway tracks, the flanges are provided to train wheelsAre you sure? This action cannot be undone. -

nice question blvn .
That's a tricky one.The vehicle taking a turn should travel at permissible speed so that it can avoid a skid or leaving a track and going for a centripetal force.
This link gives a brief idea if the permissible speed was neglected : m.bbc.co.uk/news/world-europe-23982566Are you sure? This action cannot be undone. -

@#-Link-Snipped-# : Its not only about the centrifugal force, but this design of wheels also act as a differential for the driven wheels. Locomotive's drive train does not have a differential mechanism so maintaining speed difference between outer and inner wheels during a turn would have been a problem but this simple and innovative design of track and wheels solve it. This design of wheels also helps in improving stability of trains especially by preventing swaying due to side thrust.Are you sure? This action cannot be undone.
