In previous Minecraft versions, it has been possible to obtain floating rails through a few different methods.

Obtaining

Tick Pulse

In Minecraft version 1.4.5, you must push rails with a 1 tick pulse. This would result in them staying in the air floating.

Update Suppression

Warning: Game Crash 

This feature can crash the game. Perform at your own risk.

Another (yet much more complicated) way to obtain floating rails is with Update Suppression. Example here.

23w13a_or_b less_interaction_updates Vote Rule

Warning: April Fools' 

This feature requires the usage of April Fools' versions, often requiring file renaming or file deletion to load. See the help page for information on loading these versions.

Additionally, you can obtain floating rails with the less_interaction_updates vote rule. To do this, simply enable the vote rule before placing the rails on any block. Then, simply break the block, and due to the less_interaction_updates vote rule, the rails will stay in place, making them float.

Update Skipping

Another way to obtain floating rails is through Update Skipping.

Vanishing Blocks

Finally, the last way to obtain floating rails is with Vanishing Blocks.
