Signaling in the railway is how they know what trains are where and when. There are a few different types of signaling system, but destroying any part of it will bring everything to a halt until the problem is fixed.
If a signaling system were to be destroyed or disabled no one would need to physically stay there blocking trains only to be arrested.
