⚡ Pantograph and Catenary: Wave Speed, Doppler Factor and Contact Force (3D Blender Rig)

3D pantograph-catenary lab: wire tension, dropper count and head properties set the contact force; watch waves ahead of the pantograph, the Doppler factor and arcing near the wire wave speed.

⚙ Under the hood

3D pantograph rig built in Blender: a locomotive pantograph slides under a tensioned contact wire; waves, droppers, contact force and arcing near the wire wave speed are simulated live.
