Here is a track switch out at Promontory, Utah.

This is the frog end of the switch

Closer to the points now.

Looking at the points end of the switch

Notice the ends are not pointed.  No part of the double rail section moves.

The Control arm and signal.  It's just a locking lever with a signal bar on top

The rail marked with arrows moves.   It floats (not spiked down) and has spacers to keep the rails the correct distance apart.

This is the type of switch that would have been used in 1869 as it required only 2 rails to be curved, no cutting or sharpening of points, and 2 guard rails and a frog.  With a locking control bar for the slide, switch would have to be set each direction, but simplicity itself.

Hello, Curt,
thank you for these interesting pictures, which reveal historical solutions for the installation of switches. These give me a new perspective on the technical art of engineering that was possible in the past - simple but accurate.
I am enthusiastic about the ingenuity of the former railway engineers,
many greetings from
Henry
