[1.14.4] How do I remove block collisions?

[StefanDeSterke]

I want to create a mod that implements a new type of rails, but how do I remove the collision for the rails? Vanilla Minecraft rails have disabled collisions so you can walk through them, but my rails currently have a collision just like one layer of snow on the ground does. I have checked the AbstractRailBlock and RailBlock classes of Forge but I couldn't find anything. Overriding the method getCollisionBoundingBoxFromPool and returning null doesn't work either because it doesn't exist anymore. Does anyone have an idea of how to do this?

Nevermind I already found a previous post that worked.
