Mechanical Engineering/Modeling a Single Train running on three rails.


Train running on two rails
Train running on two r  
Dear Aroosh

Will there be advantages in modeling a train running on three rails instead of two rails ?.

I Feel the advantage would be carrying more people capacity for a compromise of Train manufacturing cost incurred.

All Trains run on two rails. Now the same train will be running on three rails.

Merits : Length and Height of the train remains the same, adding a new rail 3 for the single train will result in increase of train width. Now the Load (People, Luggage) carrying capacity will increase. i.e. More People can commute / travel in the train.

Demerits : Manufacturing cost = Raw Materials cost + Labour cost. Manufacturing cost for the New Train construction to run on three rails will increase.

Awaiting your reply,

Thanks & Regards,

Hi Prashant

I have to disagree, more capacity will slow things down, it is better to be faster for smaller group of people rather than slower for larger group.
from other hand I donít know how you can distribute the weight on 3 legs "in a row" equally, you wonít be able to make a precision rail road system, for this reason to me two rail is still ideal.

Question everything
Good Luck
