AI Thread Summary
Simpack can be used to change rail profiles by simulating different rail types, such as UIC60 and 54R1, along a track. Users can also simulate pantograph contact with electric car lines to analyze performance. Resources like 4realsim and railway-fasteners provide additional information on rail types and joint bars. The discussion highlights the need for familiarity with specific rail engineering concepts and software capabilities. Engaging with these tools can enhance understanding and application in rail design and simulation.

1. How to use Simpack change the profiles of rail , for example , one 100m rail track , half rail's type is UIC60 , half rail's type is 54R1 .
2. How to use Simpack simulate pantograph contact electric-car line.

thanks, i will see that later,if i have any questions,i will let you know.
(Actually, the links were for the benefit of responders. :wink: You already know what Simpack and uic60s are.)

I have Mass A being pulled vertically. I have Mass B on an incline that is pulling Mass A. There is a 2:1 pulley between them. The math I'm using is: FA = MA / 2 = ? t-force MB * SIN(of the incline degree) = ? If MB is greater then FA, it pulls FA up as MB moves down the incline. BUT... If I reverse the 2:1 pulley. Then the math changes to... FA = MA * 2 = ? t-force MB * SIN(of the incline degree) = ? If FA is greater then MB, it pulls MB up the incline as FA moves down. It's confusing...
