You have got to do a post on ‘stringing a curve’. Done by rail civil engineers who use a ‘piece of string’ (literally) to produce tangental curves, of any radius, in the field. Who needs theodolites. 👍

I highly appreciate your videos here. Hopefully you can expand beyond tracks. Keep up the good work!

Thank you, I am glad you find them useful! Is there anything specific you would like me to look into covering outside of track?

Actually I’m also teaching a bit about railways here in the Philippines. If you don’t mind I’m gonna share your videos/channel to my class. If you have topics on operations and about rolling stock as well.

The main reason for transitions is avoiding jerks on trains. Jerks a sudden changes in accelerations. On a straight line there are no side accelerations but in a curve there are such accelartions leading to centrifugal forces (inertia of masses). Clothoides are one geometry to transition. Even without cant on slow tracks train wheels will lever as part of their contact geometry between wheel and rail.

Many thanks for that information about horizontal curve 🌹 Waiting for more like vertical curve and track gradient
